The differences arose from conflicting claims of accuracy between two methods, ḥisāb (astronomical calculations) and ruʾyah (physical sighting of the moon), in determining the start of the lunar month among Muslims. Concerned about these issues, Basyūnī ‘Imrān addressed them in his manuscript written in Arabic-Malay (known as Aksara Jawī), titled Ḥusn al-Jawāb ‘an Ithbāt al-Ahillah bi al-Ḥisāb (1933). By employing a historical approach and content analysis of the manuscript, the authors find that Basyūnī ‘Imrān favoured the ḥisāb method for determining the start of the lunar month. In addition to referencing Sūrah al-Raḥmān verse 5, Sūrah Yūnus verse 5, and a hadith narrated by Imām Mālik, Basyūnī ‘Imrān also considered the geographical and social conditions of Muslims to standardise the observance of fasting and Islamic festivals in the Sultanate of Sambas and its surroundings. He argued that differences in determining the start of the lunar month should not lead to divisions among Muslims, as both methods are grounded in the same theological principles. This finding contributes to the history of Islamic legal thought in Indonesia by providing evidence of scholarly efforts to standardise the determination of the lunar month during his tenure as Mahārāja Imām in the Sultanate of Sambas from 1913 to 1976. [Artikel ini menganalisis respons Basyūnī ‘Imrān (1885-1976), muftī dan qādhī yang bergelar Mahārāja Imām di Kesultanan Sambas, terhadap polemik perbedaan dalam penentuan awal puasa Ramadhan dan hari raya Idul Fitri pada awal abad kedua puluh. Perbedaan tersebut disebabkan saling klaim kebenaran metode, antara ḥisāb dan ruʾyah, dalam penentuan awal bulan Qomariyah di kalangan umat Islam. Prihatin terhadap peristiwa tersebut, Basyūnī ‘Imrān meresponsnya sebagaimana yang tertuang dalam manuskrip berbahasa Arab-Melayu (dikenal sebagai Aksara Jawī) yang berjudul, Ḥusn al-Jawāb ‘an Ithbāt al-Ahillah bi al-Ḥisāb (1933). Dengan menggunakan pendekatan sejarah dan analisis konten manuskrip, para penulis menemukan bahwa Basyūnī ‘Imrān cenderung menggunakan metode ḥisāb dalam penentuan awal bulan Qomariyah.

Selain merujuk pada Sūrah al-Raḥmān ayat 5, Sūrah Yūnus ayat 5, dan sebuah hadis yang diriwayatkan oleh Imām Mālik, Basyūnī ‘Imrān juga mempertimbangkan kondisi geografis dan sosial umat Islam untuk menyeragamkan pelaksanaan ibadah puasa dan hari raya Islam di Kesultanan Sambas dan sekitarnya. Menurutnya, perbedaan dalam penentuan awal bulan tersebut tidak boleh menimbulkan perpecahan di antara umat Islam, karena kedua metode tersebut berlandaskan pada dasar teologi yang sama. Temuan ini berkontribusi terhadap sejarah pemikiran hukum Islam di Indonesia dengan memberikan bukti adanya pemikiran ulama yang berupaya menyeragamkan penentuan awal bulan Qomariyah yang diterapkannya ketika menjabat sebagai Mahārāja Imām di Kesultanan Sambas pada tahun 1913 sampai 1976.] Keywords: Basyūnī ‘Imrān, Ḥisāb Method, Islamic Astronomy, Qamariyah Month, Sambas Sultanate. Introduction Ramaḍān and Shawwāl are two months in the Islamic (Hijri) calendar with significant spiritual, cultural, and social dimensions for Muslims worldwide.1 However, there are often differences in determining the start of these months.2 These discrepancies arise from the varying methods and criteria employed by different countries.3 On December 8, 2021, four countries, Malaysia, Brunei, Indonesia, and Singapore (MABIMS), implemented new crescent moon visibility criteria to determine the beginning of the Qamariyah months (lunar).4 Although these countries share the same criteria and theological foundations, differences in scholars’ interpretations have resulted in two primary methods for determining the onset of the lunar months: ḥisāb (astronomical calculations) and ruʾyah (physical moon sighting).5 Each group within the Muslim community asserts that their chosen method aligns most accurately with Shari’ah.6 These differing approaches have the potential to cause discord among Muslims.7 In Indonesia, the polemic over determining the beginning of the months of Ramaḍān and Shaw has persisted since the early 20th century, with ongoing debates among Indonesian 1 2 3 4 5 6 7 Jaffer Idris, Charlotte Rowley, and M.

He held the titles of muftī and qādhī, as well as Mahārāja Imām (the highest religious official) and advisor on Islamic affairs to the Sultanate of Sambas, having been appointed on November 9, 1913 (10 Dhū al-Ḥijjah 1331).10 His response is documented in his work, Ḥusn al-Jawāb ‘an Ithbāt al-Ahillah bi al-Ḥisāb. This manuscript reflects his concern over the divisions among Islamic groups, each claiming superiority in their method for determining the beginning of the months. Basyūnī ‘Imrān argued that the differences in these methods should not lead to division among Muslims, as both are based on the same theological foundation.11 Consequently, his thoughts, as presented in this manuscript, warrant further analysis in this article. Research on the thoughts and works of scholars from the Borneo remains relatively limited. Some scholars have examined the writings of Muḥammad Arshad al-Banjarī,12 Ismail Mundu,13 and Basyūnī ‘Imrān. Previous studies on Basyūnī ‘Imrān have primarily focused on three areas: education,14 tafsīr (Qur’anic exegesis),15 and fiqh (Islamic jurisprudence).16 These studies highlight that Basyūnī ‘Imrān significantly contributed to the advancement of Islam 8 9 10 11 12 13 14 15 16 Azmi Muttaqin, “Determination of the Beginning of Ramadhan and Syawal in Indonesia (An Overview of Political and Historical Perspectives),” Journal of Islamic Studies and Humanities 7, no. 2 (2022): 131–47.

However, unlike scholars who have focused on his contributions to fiqh, this article explores his work in Islamic astronomy (ʿilm al-falak), specifically his treatise Ḥusn al-Jawāb ‘an Ithbāt al-Ahillah bi al-Ḥisāb. While Hamka Siregar asserts that Basyūnī ‘Imrān adhered to the Shāfi’ī school of thought,17 which accepts both ruʾyah and ḥisāb as valid methods,18 Basyūnī ‘Imrān prioritised the ḥisāb method over ruʾyah in determining the beginning of the Qamariyah months, considering the geographical and social conditions of Sambas. His preference for the ḥisāb method was intended to address the ongoing debates among scholars of his time and to prevent potential conflicts within the Muslim community. Therefore, this article builds upon previous studies on Basyūnī ‘Imrān’s fiqh-related works by focusing on his contributions to ʿilm al-falak, an area that has received little scholarly attention. This article is a philological study employing a historical approach. The primary source for this research is Basyūnī ‘Imrān’s Ḥusn al-Jawāb ’an Ithbāt al-Ahillah bī al-Ḥisāb. The philological analysis involved transliterating the manuscript, originally written in the Jawī script (Malay-Arabic script), into Indonesian and identifying both the physical characteristics and the content of the text. After the transliteration, the authors conducted a substantive analysis of the manuscript using a historical approach. Additionally, the authors consulted various research findings, scholarly articles, and relevant Islamic texts as secondary sources to aid in the historical analysis of the manuscript. These steps were undertaken to provide a comprehensive understanding of Basyūnī ‘Imrān’s views on the determination of the Qamariyah months, as well as the historical background and context in which the manuscript was written. Basyūnī ‘Imrān: Muftī and Qādhī in the Sultanate of Sambas Basyūnī ‘Imrān was born in Sambas on October 16, 1885, with the full name H. Mohd. Basioeni bin H. Imran. His father, Muḥammad ‘Imrān, held the position of Mahārāja Imām in the Malay Sultanate of Sambas.19 Basyūnī ‘Imrān received his early education at a colonial primary school (volksschool) in Sambas and was first taught religious studies by his father, focusing on the Arabic language, Qur’anic recitation, and fiqh. At the age of 17, in 1902, his father sent him to Mecca to further his religious education. There, Basyūnī ‘Imrān studied under prominent Malay scholars such as ‘Umar al-Sumbawī, ‘Uthmān al-Sarawākī alPuntiyānī, and Aḥmad Khaṭīb Minangkabāwī. He also studied various other disciplines, including logic, uṣūl al-fiqh (principles of Islamic jurisprudence), hadith, tafsīr, and Islamic 17 18 19 Siregar, “Dynamics of Local Islam,” 187–202.

After nearly five years of study in Mecca, Basyūnī ‘Imrān returned to Sambas in 1906.20 In 1910, Basyūnī ‘Imrān travelled to Cairo with his brother, Ahmad Fawzi, and his friend, Ahmad Sa’ud. They enrolled in a newly established school founded by Rashīd Riḍā, Dār al-Daʿwah wa al-Irshād. Upon their arrival in Cairo, they were met by Şālih Riḍā and taken to his brother Rashīd’s house, where they stayed until suitable accommodation was found in another apartment owned by Rashīd. During their meeting, Rashīd inquired about the state of scholarship among Javanese scholars and praised Basyūnī ‘Imrān for his excellent command of Arabic. Basyūnī ‘Imrān remained in Cairo for three years before returning to Sambas in 1913.21 Figure 1 Mahārāja Imām Kesultanan Sambas (1913-1976) Source: Syahrul Hidayat dan Kevin W. Fogg, 2018. After completing his Islamic education in the Middle East, Basyūnī ‘Imrān held several key religious positions in Sambas. In 1906, he was appointed Imām of the Sambas Jami’ Mosque and served as a religious educator for the Sultan’s family at the Sambas Sultanate Palace. Upon his return from Cairo in 1913, he was appointed as muftī and qādhī of the Sambas Sultanate, with the title Mahārāja Imām, succeeding his late father.22 This appointment was made by M. Tsafiuddin II, the 13th Sultan of the Sambas Sultanate. Basyūnī ‘Imrān served in these roles from November 9, 1913, until his death on July 26, 1976.23 In addition to his positions within the Sultanate, he also served as Adviseur Bestuur Commissie Swapradja Sambas (1946–1951) and Head of the Religious Court Office for Singkawang and 20 21 22 23 Martin van Bruinessen, “Basyuni ‘Imran (Muhammad Basyuni b.

Sambas (1951–1952).24 Basyūnī ‘Imrān passed away in Pontianak at the age of 91 and was buried in Sambas.25 Basyūnī ‘Imrān’s deep concern over the decline and stagnation of Muslims in various parts of the world established him as a scholar not only respected by the local Muslim community26 but also influential within the broader Islamic world.27 It was demonstrated when he sent a letter to Rashīd Riḍā posing the question, limādhā ta’akhkhara al-muslimūn wa limādhā taqaddama ghayruhum (why are Muslims falling behind while others are advancing?). Rashīd Riḍā subsequently presented this question to Amīr Shakīb Arslān, who responded by producing a treatise that examined the causes of Muslim decline in contrast to the rapid progress of other nations.28 While serving as muftī and qādhī, Basyūnī ‘Imrān maintained correspondence with Rashīd Riḍā through al-Manār,29 a magazine that Rashīd used to disseminate his ideas on modernism, reform, and the revival of the Muslim ummah through insightful essays.30 One of the letters Basyūnī sent to Rashīd was a request for a fatwa (istiftā) regarding Tjokroaminoto’s proposal to translate Muḥammad ‘Alī’s Qur’an, a topic that sparked intense debate during the Al-Islam Congress in 1928. The Muhammadiyah delegation suggested a debate between ʿAlī and Rashīd to discuss Muḥammad ʿAlī’s translation, but this proposal was rejected by the Congress. Instead, Basyūnī ‘Imrān sought Rashīd’s fatwa on the matter.31 In addition to this, Basyūnī ‘Imrān submitted questions to Rashīd via al-Manār concerning the comparison of education in Egypt and Europe. He raised three key questions: First, are Egyptian secondary schools comparable to those in England, France, Germany, Switzerland, the Netherlands, and other European countries in terms of science, arts, and languages, apart from Arabic and Islamic studies?

Furthermore, Basyūnī ‘Imrān also sought Rashīd’s opinion on whether nationalism was compatible with Islam. In al-Manār, Rashīd responded affirmatively, basing his view on the principle hubb al-watan min al-īmān (love of country is part of faith). This endorsement of nationalism by Rashīd Riḍā was subsequently embraced by Indonesian scholars, who came to view nationalism as compatible with Islamic principles.33 Inspired by nationalism, the people of Sambas established the Sambas Indonesian Nation Association (Persatuan Bangsa Indonesia Sambas [PERBIS]) and actively resisted colonial rule in the lead-up to Indonesian independence. On October 27, 1945, they approached the Dutch administration, demanding that the Dutch lower their flag to recognise Indonesia’s independence. The following day, they assembled at the theatre building, where Basyūnī ‘Imrān delivered a speech urging the people of Sambas to continue their struggle until the Dutch flag was replaced by the Indonesian red and white flag. After Sambas became part of the Republic of Indonesia and was situated near Malaysia,34 Basyūnī ‘Imrān directed his political activities through the Indonesian Muslim Brotherhood (Masyumi). During the Old Order, one of Masyumi’s early initiatives was to establish Islam as the foundation of the state, but this effort failed due to internal factors, including communist ideology, nationalism, and secularism.35 In the Constituent Assembly following the first general election, Basyūnī ‘Imrān was elected as a representative of Masyumi West Kalimantan, holding member number 305. In 1959, he, along with other scholars, was invited to a national conference to examine errors in the Qur’anic texts circulating at the time, during which he identified several inaccuracies.36 In addition to his roles as muftī and qādhī, Basyūnī ‘Imrān was a prolific scholar with a diverse body of work spanning the fields of fiqh, tawḥīd, history, falak, and other areas. According to Syarif’s research, he authored fifteen notable works, including: Tarjamah Durūs 32 33 34 35 36 Mona Abaza, “Southeast Asia and the Middle East: Al-Manar and Islamic Modernity,” in From the Mediterranean to the China Sea: Miscellaneous Notes, ed.

This achievement led to Basyūnī ‘Imrān receiving an accolade from President Soekarno in the form of a Qur’an enclosed in a meticulously calligraphed box.

Basyūnī ‘Imrān’s authority in the social construction of Sambas society notably influenced its socio-religious aspects, particularly regarding daily religious practices. The role of muftī and qādhī, initially a position serving the sultanate family exclusively, evolved under his leadership to encompass the broader Muslim community in Sambas.38 Basyūnī ‘Imrān exhibited a tolerant and moderate approach39 in his thinking and daily life. His friendly demeanour extended to everyone, including clergy who visited him during Eid al-Fitr. In the political arena, Basyūnī ‘Imrān demonstrated an openness to various groups beyond his own affiliation. It was exemplified by his support for Firdaus, a candidate from the Partai Nasional Indonesia (Indonesian National Party [PNI]), during the Sambas Regent election, despite his own association with the Masyumi party. Basyūnī ‘Imrān endorsed Firdaus on the grounds of his relevant experience in government, religious observance, and his close relationship with the Sultan of Sambas.40 Basyūnī ‘Imrān on Ḥisāb Method for Determining the Qamariyah Month The manuscript analysed in this article is titled in two languages. In Arabic, it is called Ḥusn al-Jawāb ‘an Ithbāt al-Ahillah bi al-Ḥisāb, and in Malay, it is titled Molek Jawaban pada Mengitsbatkan Awal Bulan dengan Kiraan. The title can be translated in English as Beautiful Answer in Determining the Beginning of the Month with Ḥisāb. Basyūnī ‘Imrān wrote the manuscript on 23 December 1933 CE (6 Ramaḍān 1352 AH) and completed it on 3 February 1937 CE (21 Dhū al-Ḥijjah 1355 AH).

Wan Mohd Shaghir Abdullah, 2022. This manuscript consists of four sections. The first section discusses the concepts of hilāl (crescent moon), qamar (moon), and shahr (month). The second section addresses the origins of using numerical calculations for timekeeping. The third section explores the benefits of using ruʾyah (sighting of the moon) as prescribed by Sharīʿah for determining the times of worship. The fourth section focuses43 on the use of ḥisāb (calculation) for determining all times of worship. These four discussions are written in Arabic-Malay, also known as Jawī script.44 The manuscript measures 18.2 cm in length and 13.4 cm in width, with a total of 28 pages. In addition to an introduction by Shaykh Ṭāhir Jalāl al-Dīn alMinkābī, the manuscript includes a preface by Basyūnī ‘Imrān that explains the context and motivation behind its composition. In the introduction of Ḥusn al-Jawāb ‘an Ithbāt al-Ahillah bi al-Ḥisāb, Basyūnī ’Imrān addresses the disputes among scholars and their followers over the use of ḥisāb or ruʾyah to determine the beginning of Ramaḍān and Shawwāl. He argues that such disagreements are harmful to the Muslim community, as they could foster negative perceptions among nonMuslims due to differing dates for fasting and Eid al-Fitr. Basyūnī ’Imrān believes these disputes should not cause division, as both methods are rooted in the same religious texts. Instead, he stresses the importance of consensus in determining the start of the month. In the manuscript, he favours the ḥisāb method over ruʾyah, as it aligns better with the 43 44 ‘Imrān, Ḥusn al-Jawāb ‘an Ithbāt al-Ahillah bi al-Ḥisāb, 1-2 Manuscripts written in Jawi script played a significant role in shaping the beliefs and knowledge of the Muslim community in Indonesia.

[ 230 ] Herlambang et al. geographical and social context of the Muslim communities in Borneo, particularly in the Sambas, Mempawah, and Pontianak Sultanates.45 Why Did Basyūnī ‘Imrān Choose the Ḥisāb Method? Two factors led Basyūnī ‘Imrān to favour the ḥisāb method over ruʾyah for determining the Qamariyah month in the Sambas Sultanate. The first factor was the region’s geographical conditions, as the area was frequently affected by rain, making it difficult for scholars and authorities to observe the hilāl. As a result, the ḥisāb method was used to determine the beginning of Ramaḍān and Shawwāl. He argued that there should be no doubt (shakk) in using ḥisāb for determining the start of Ramaḍān and the other 11 months, especially when this determination is made by the leader (amīr). He emphasised that when Imāms, kings, or amīrs announce the beginning of the Qamariyah month using ḥisāb, it becomes a binding decree for Muslims.46 The second factor is the social condition of the Muslim community in the Sambas Sultanate, which lacked sufficient Islamic knowledge. Although the ruʾyah al-hilāl (crescent moon sighting) method is based on the Hadith, “Do not fast until you see the hilāl,” another hadith also states, “We are ummi people, neither writing nor calculating (ḥisāb). The month is sometimes 29 or 30 days”. Based on these two traditions, Basyūnī ‘Imrān concludes that during the Prophet Muhammad’s time, Muslims were ummī (unlettered), so they relied on ruʾyah al-hilāl to determine the beginning of the Hijri month.47 However, the Prophet was also commanded to lead his people out of ignorance. Therefore, learning ḥisāb is essential to move beyond the ummī condition, as it allows Muslims to progress through knowledge and overcome backwardness. Basyūnī ‘Imrān states:48 “The claim that there were no experts in ḥisāb contradicts the apparent meaning of the Hadith, which states that the Ummah is ummiyah (unfamiliar with ḥisāb). However, the Prophet (peace and blessings be upon him) was sent to guide the Ummah out of such ignorance, as indicated by the Qur’anic text. Thus, it is unreasonable to suggest that the Ummah should be commended to follow something it has no knowledge of. If there had been individuals with expertise in ḥisāb during that time, it would have been valid, and perhaps even obligatory, to rely on their knowledge. However, this should not be confused with the assertions of most astrologers, whose conclusions are often based on speculation and are not definitive (qath’i).” Basyūnī ‘Imrān’s view aligns with that of Yūsuf al-Qaraḍāwī, who argues that Muslims today are no longer ummī but have mastered the science of astronomy. This mastery not only aids in determining the start of the Qamariyah month but also in calculating the Qibla direction.49 Al-Qaraḍāwī asserts that ḥisāb should be used alongside ruʾyah to determine the 45 46 47 48 49 ‘Imrān, Ḥusn al-Jawāb ‘an Ithbāt al-Ahillah bi al-Ḥisāb, 1–2. ‘Imrān, Ḥusn al-Jawāb ‘an Ithbāt al-Ahillah bi al-Ḥisāb, 25–8.

[ 231 ] Herlambang et al. beginning of the Hijri month unless no astronomer is available in a particular location. Similarly, Basyūnī ‘Imrān’s perspective is in line with Muhammadiyah’s, which holds that ruʾyah is no longer valid because its legal rationale (‘illah) based on the ummī status of the Muslim community has ceased to exist. Today, many Muslims possess astronomical knowledge and can calculate the beginning of the Qamariyah month. Consequently, with the disappearance of the legal ‘illah, the reliance on ruʾyah is no longer relevant.50 Muhammadiyah’s position reflects its responsibility in addressing contemporary religious issues within the Muslim community.51 The data indicates that Basyūnī ‘Imrān favoured the ḥisāb method for determining the Qamariyah month in the Sambas Sultanate. Two key factors influenced his preference for ḥisāb over ruʾyah. First, the geographical conditions of the Sambas Sultanate, which are frequently affected by rain, hindered the visibility of the hilāl. Second, the social conditions of the local Muslim community, which lacked sufficient Islamic knowledge, further supported his preference for ḥisāb. As a muftī and qādhī with the title Mahārāja Imām, Basyūnī ‘Imrān mandated the use of the ḥisāb method for determining the Qamariyah month, a decision that extended to the Sambas Sultanate, Mempawah, and Pontianak areas.52 His endorsement of the ḥisāb method indirectly encouraged the Muslim community in the Sambas Sultanate to engage with scientific knowledge, including reading, writing, and arithmetic. In addition to his preference for the ḥisāb method over ruʾyah, Basyūnī ‘Imrān’s practical contribution lies in his ability to unify Muslims in the Sambas Sultanate regarding the determination of the months of Ramaḍān and Shawwāl. He argued that Muslims should preserve their unity, as both methods are grounded in religious texts. Consequently, Muslims should avoid division and mutual condemnation, regardless of their location. According to Basyūnī ‘Imrān, the different methods for determining the Qamariyah month do not negatively impact fasting or prayer.53 His perspective underscores the importance of maintaining Muslim brotherhood despite differences in the methods of determining the Qamariyah month. Basyūnī ‘Imrān’s Islamic Legal Reasoning for Determining the Qamariyah Month Basyūnī ‘Imrān preferred using the ḥisāb method over ruʾyah for determining the Qamariyah month. This preference is grounded in his interpretation of Sūrah al-Raḥmān, verse 5, Sūrah Yūnus, verse 5, and a hadith narrated by Imām Mālik. Sūrah al-Raḥmān, verse 5, states, “The sun and the moon move according to calculation.” In contrast, Sūrah Yūnus, verse 5, reads, “It is He 50 51 52 53 Astronomy References in Indonesia,” AHKAM: Jurnal Ilmu Syariah 22, no. 2 (31 December 2022): 385–410; Hosen et al., “Tagyîr Mawdhî’ Inhirâf Qiblat al-Masjid fî Bamîkasân ‘alâ Asasi al-Tiknôlôjiyya alMutaqaddimah: al-Tahlîla al-Ijtimâ’î wa al-Tsaqafî,” AL-IHKAM: Jurnal Hukum & Pranata Sosial 18, no. 2 (2023): 591–625.

Allah has not created this except in truth. He explains the signs to people who know.” Basyūnī ‘Imrān argues that these verses highlight the importance of distinguishing ḥisāb from astrology, which he views as imprecise and largely speculative. According to him, while astrology often provides uncertain or hidden information, the science of ḥisāb, when conducted by experts, offers a more accurate and beneficial method for determining the Qamariyah month. Based on Sūrah al-Raḥmān, verse 5, and Sūrah Yūnus, verse 5, astrology is distinguished from ḥisāb. Hamka, in Tafsir al-Azhar, explains that Sūrah al-Raḥmān, verse 5, describes the sun and moon’s movements as occurring with precise calculation. The Earth orbits the moon over the course of 365 days, while the lunar year is 354 days due to a discrepancy of approximately 11 days.54 Sūrah Yūnus, verse 5, discusses the consistent movement of the moon and the necessity of understanding its orbital parameters. Hamka asserts that the concept of calculation (ḥisāb) is integral to understanding these celestial phenomena.55 Although initially favouring the ḥisāb method, Hamka eventually opted for the ruʾyah method in determining the beginning of the Qamariyah month.56 This shift highlights Hamka’s engagement with scientific reasoning in his interpretation of Quranic verses, reflecting his reputation as a rational and critical mufassir.57 In addition to these two verses, Basyūnī ‘Imrān reinforced his argument by citing a hadith narrated by Imām Mālik. This hadith discusses the observation of the moon for determining the start of Ramaḍān and states, “Lā taṣūmū ḥattā tarawū al-hilāl wa lā tufṭirū ḥattā tarawhu fa-in ghumm ʿalaykum faqdurū lah” (Do not fast until you see the hilāl, and do not break your fast until you see it; but if the hilāl is obscured, then estimate it).58 Basyūnī ‘Imrān interprets the term “faqdurūlah” as an instruction to use the ḥisāb method if an expert is available. According to him, if a ḥisāb expert is present, the use of ḥisāb is permissible and advisable, as ḥisāb is considered an exact science (qaṭʿī). If no ḥisāb expert is available, the month should be completed in 30 days.59 In the context of the Sambas Sultanate, Basyūnī ‘Imrān contended that once a ḥisāb expert is available, there is no need to debate or question the application of the ḥisāb method for determining the beginning of the Qamariyah month. He argued that the use of the ḥisāb method offers significant benefits for scientific accuracy under all conditions.

[ 233 ] Herlambang et al. ḥisāb method was not employed during the Salaf period, advancements in contemporary science justify its use today.60 Basyūnī ‘Imrān asserts:61 “In the context of ḥisāb (astronomical calculations), it is noted that this method did not exist during the time of the Salaf, who reached a consensus (ijmaʿ) on this matter. It is now understood that this consensus permits the use of ḥisāb and that it should not be disregarded. Specifically, it is not permissible to rely solely on moon sightings in the evening if the astronomer, who uses ḥisāb, determines that visibility of the moon cannot be established. Thus, when determining the time for the month (hilāl), it is essential to consider the sun’s position at the end of the month (shahr), including hours and minutes. Furthermore, if individuals only partially observe the moon but cannot confirm the beginning of the month, they should not unilaterally declare the start of the month for everyone.” Basyūnī ‘Imrān’s viewpoint aligns with that of Taqī al-Dīn al-Subkī, who argued that fasting based on ḥisāb is permissible. According to al-Subkī, if the crescent moon is reported to have appeared but ḥisāb calculations, which are considered definitive (qaṭʿī), indicate that the crescent moon should not be visible, then such testimony (shahādah) should be deemed invalid and rejected. In the context of fiqh, shahādah must be supported by an oath and concrete evidence. At the same time, in the realm of astronomy, shahādah must be based on accurate measurements of external factors such as weather, climate, and environmental conditions.62 For al-Subkī, the value of news (khabar) and testimony is considered probabilistic (ẓannī), whereas ḥisāb is definitive (qaṭʿī). Thus, definitive evidence cannot be contradicted by probabilistic information (ẓannī). 63 In addition to referring to Sūrah al-Raḥmān verse 5, Sūrah Yūnus verse 5, and a hadith narrated by Imām Mālik, Basyūnī ‘Imrān also considered the geographical and social conditions of Muslims in the Sambas Sultanate when determining the use of the ḥisāb method for establishing the Qamariyah month. This approach demonstrates Basyūnī ‘Imrān’s moderate style of Islamic legal reasoning, which integrates both normative and empirical approaches. Jaelani and Risa observe that while Basyūnī ‘Imrān’s jurisprudential views align with the opinions of the four Sunnī schools of thought, particularly the Shāfi’ī school, he exhibits a degree of independent thought that diverges from mainstream Shāfi’ī views. 64 It is 60 61 62 63 64 ‘Imrān, Ḥusn al-Jawāb ‘an Ithbāt al-Ahillah bi al-Ḥisāb, 20. ‘Imrān, Ḥusn al-Jawāb ‘an Ithbāt al-Ahillah bi al-Ḥisāb, 20–1.

Muhammad Rahmatullah notes that Basyūnī ‘Imrān sometimes adopts a rationalist stance but can also exhibit literal and textual interpretations.65 Zulfkifli highlights that Basyūnī ‘Imrān’s application of the ḥisāb method for determining the Qamariyah month reflects an adaptation to the socio-cultural context of the Sambas Sultanate, aiming to prevent mere imitation and fanaticism by re-opening the door to ijtihād.66 Conclusion This article concludes that Basyūnī ‘Imrān preferred the ḥisāb method over the ruʾyah method for determining the start of the Qamariyah month in the Sambas Sultanate. This preference is based on two primary factors: the region’s frequent rainfall, which impedes the observation of the hilāl, and the local Muslim community’s insufficient religious knowledge. In addition to these factors, Basyūnī ‘Imrān also draws on Sūrah al-Raḥmān verse 5, Sūrah Yūnus verse 5, and a hadith narrated by Imām Mālik to standardise the practices of fasting and Islamic holidays in the Sambas Sultanate and its environs. Basyūnī ‘Imrān contended that the ḥisāb method was better suited to contemporary conditions and societal needs and could advance scientific understanding among Muslims without compromising religious principles. His application of the ḥisāb method in determining the beginning of the Qamariyah month was in effect during his tenure as mufti and qādhi in the Sambas Sultanate from 1913 to 1976. The limitations of this study are primarily due to its specific focus on the context of the Sambas Sultanate and the work of Basyūnī ‘Imrān. As a result, the findings may not be fully applicable to other regions or communities with differing geographical and social conditions. Nevertheless, the study suggests that Basyūnī ‘Imrān’s moderate approach, integrating the ḥisāb method while considering local conditions, could serve as a model for other scholars in applying Islamic law in a manner that aligns with scientific advancements and local community needs. Furthermore, this approach has the potential to mitigate divisions among Muslims regarding the determination of the Qamariyah month by underscoring the importance of deliberation and community unity.
