THE ROLE OF S-O-R THEORY Abdul Nasser Hasibuan1. Ahmad Afandi2 and Windari3 1, 2, 3 Syekh Ali Hasan Ahmad Addary State Islamic University Padangsidimpuan. Indonesia ABSTRACT The growth of e-commerce has not only expanded the Muslim fashion industry but also fostered impulsive buying among customers. This article analyses the behaviour of Muslim customers using the S-O-R model to detect impulsive buying and subsequently post-purchase regret. In the analysis, we consider the role of religiosity in the link between the two. We collect data via self-administered questionnaires from 312 Muslim respondents and apply Partial Least Square structural equation modelling (PLS-SEM) to analyse the data using AMOS version 24. The results suggest that scarcity cues, fear of missing out, and live commerce have a significant influence on impulsive buying. Additionally, scarcity cues can lead to fear of missing out, based on their positive worth. The impulsive buying also invariably culminates in postpurchase regret. However, religion weakens the link between impulsive buying and post-purchase regret. Religiosity also reduces post-purchase regret. The results of our study can help authorities in understanding purchasing behavior of Muslims and consequently crafting initiatives to encourage purposeful purchase of fashions by Muslims.

The Role of S-O-R Theory INTRODUCTION The emergence of online shopping has made it easier for some to purchase products without having to meet face-to-face with sellers (Wang et al. , 2022. Sharabati et al. In general, online shopping activities are carried out by various sections of the community. In the Beyond the Digital Frontier research report. KIC estimates that in Indonesia 33. 4% of the population are active e-commerce consumers while 17% of the population are occasional users and the remaining 49. 6% are non-ecommerce users (Ahdiat, 2. Globally, 59% of consumers prefer to shop online, while the remaining 41% prefer shopping in stores (Cassetti, 2. In 2023, e-commerce transactions in Indonesia increased by 4. 99% and sale volumes through e-commerce reached 361. 54 million (Kusnindar et al. , 2. This indicates that consumer sales via e-commerce have grown in recent years, albeit 4% of the population being active users. E-commerce is expected to be the largest contributing sector to the digital economy in Indonesia based on a recent report by Google. Temasek, and Bain & Company entitled e-Conomy SEA 2023 (Hoppe et al. , 2. The Gross Merchandise Value (GMV) of IndonesiaAos digital economy in the e-commerce sector is estimated at US$62 billion for 2023. The development of the Internet potentially encourages impulsive online shopping behavior among the public (Ardiyanti, 2023. Ming et al. , 2. Impulsive Buying is defined as spontaneous and immediate purchases of a product without a mature and considerate evaluation of alternatives or future repercussions (Nurohman & Aziz, 2021. Rahmawati & Primanto, 2021. Rizki et al. , 2022. Rook. Rook & Fisher, 1. Impulsive buying is also referred as unexpected purchases or unreasonable conduct (Li et al. , 2. According to Usadi et al. and Nugraha et al. , roughly 47% of impulsive consumers claim they are heavily attracted to bargains as well as bids, which are the greatest reasons for Accordingly, a study on impulsive buying is relevant, given the rise of impulsive buying in e-commerce. Indonesia is a country with the largest Muslim population, with 87% of 254 million population being Muslims (Usadi et al. , 2. This makes Indonesia the third-largest Muslim fashion consumers in the world with sales exceeding 20 billion dollars or 300 trillion rupiah (Nugraha et al. , 2. Muslim fashion trends themselves can create an identity that is obedient and yet fashionable and stylish (Nurani & Adinugraha, 2. Moreover. Indonesia has already positioned itself in 2020 as the global hub of Muslim fashion (Izza, 2. Muslim fashion maintains its popularity among consumers in the e-commerce industry (Adriyanto et al. Therefore, this research focuses on Muslim fashion products and examines the impulsive purchase behavior of customers for these products. More specifically, this research has the following objectives: . to describe Muslim behavior in buying Muslim fashion using the S-O-R (Stimulus-OrganismRespons. to determine the factors that have the highest influence on Impulsive buying. to find out whether impulsive buying ends in post-purchase and . to find out whether religiosity is a moderator of the relationship between impulsive Buying and post-purchase regret. Developed by Hoveland et al. , the S-O-R (Stimulus-Organism-Respons. model in impulsive buying has been applied by prior studies (Clouthier et al. Feng et al. , 2023. Huo et al. , 2023. Karim et al. , 2021. Li et al. , 2022. Maryati Journal of Islamic Monetary Economics and Finance. Vol. Number 3, 2025 et al. , 2020. Wang et al. , 2. The SOR model on Impulsive buying is framed in various contexts, which include web stimuli, product and marketing variations (Karim et al. , 2. , promotions (Huo et al. , 2023. Rita et al. , 2. , urgent needs (Feng et al. , 2. , hedonic lifestyle (Li et al. , 2022. Maryati et al. , 2. , and others. In the paper, we apply the SOR model to Muslim clients buying Muslim garments We extend the analysis further by examining whether impulsive buying results in regret, an aspect that is still underexplored in the literature . Nelik et al. Nurohman & Aziz, 2021. Secapramana et al. , 2. It is generally noted that regret after making a purchase is due to lack of thorough consideration and attention to detail in selecting items (Papy & Martinez, 2. This regret is often influenced by discounts (Barta et al. , 2. and the constraints of time (Kumar et al. , 2. Regret occurs when customers become aware that their purchase selections are erroneous, further inflicting loss. Again, impulsive buying behaviors influenced by materialism are believed to be an instance of postpurchase regret . Nelik et al. , 2. Therefore, preventive measures are necessary to overcome post-purchase regret. In this regard, religiosity can potentially avert impulsive buying and regret. In light of this, we also examine the role of religiousity in impulsive purchase and regret. The rest of the paper is structured as follows. In the next section, we review relevant literature. Then, section i presents the methodology, followed by presentation and discussion of results in section IV. Finally, we draw conclusions and recommendations in section V. II. LITERATURE REVIEW AND RESEARCH HYPOTHESES Background Theory The basis for this research is the S-O-R (Stimulus-Organism-Respons. theory developed by Hovland et al. It posits that sensory cues prompts consumer Stimulus (S) refers to an environmental or external cause that sparks consumer interest. Organism (O) is an internal process that happens between consciousness of stimuli and consequent action, comprised of varied senses, arousal, psychological, and mental achievements. Meanwhile, response (R) is a result of the stimulus, and the organism symbolizes the ultimate action, choice, and reaction in response (Huo et al. , 2. The S-O-R model is normally used for the following two reasons: First, the SOR model provides a complete model for comprehending how environmental stimuli (S) can cause an organism (O) to participate in psychological processes to create behavioural reactions (R) (Wang et al. , 2. And secondly, the S-O-R model provides a holistic approach in integrating multiple external cues associated to the impulsive buying (Gulfraz et al. , 2022. Zhang et al. , 2. The key variables based on the S-O-R theory are the scarcity cue, fear of missing out and live commerce. They serve as stimulants to make customers interested so that they would act accordingly. The scarcity alludes to the desire for security. The security needs can be used as a precaution because these needs cannot totally remove concern about risks such as the shortage of a product (Li et al. , 2. Live commerce will affect emotions, resulting in unforeseen actions (Zhang et al. , 2. Meanwhile, fear of missing out (FOMO), according to yNelik et al. , is an Is Impulsive Buying for Muslim Fashion Products Invariably Followed by Post-purchase Regret? The Role of S-O-R Theory emotion used to define customersAo anxieties about losing out on opportunities or experiences that others have had. Previous Studies Clover . is perhaps the first study on impulsive purchase, which has since attracted substantial interest from scholars to examine impulsive buying. In a recent bibliometric analysis. Bashar et al. analyse 482 research papers from 2000 to 2020 using Scopus database. As it provides us with a comprehensive picture on such information as co-citations, co-occurrences, frequent searches and others (Rusydiana, 2. , we follow Bashar et al. by analysing 200 related research works published in 2008 to 2021 as a review of the literature. Articles are assessed by VOSViewer based on co-occurence analysis with the counting technique of total counting. Through the results of the VOSViewer, it is noted that there are not many articles addressing buying without thinking in terms of impulsive buying, food waste, grocery shopping, scarcity, discounts, live streaming commerce, customers, and others . ee Figure . The Network Visualization graphic also illustrates that numerous studies on impulsive buying focus on sales promotion. Impulsive buying behavior, e-commerce, and so on. Figure 1. Network Visualization Journal of Islamic Monetary Economics and Finance. Vol. Number 3, 2025 Furthermore. Overlay Visualization demonstrates that most research is from mid-2019 to 2020. The topics explored in the most recent years are indicated in yellow in Figure 2. The Figure shows that the newest studies on impulsive buying focuses on e-commerce, scarcity, pls-sem, buying tedency, live streaming commerce, and discounts. However, there are still several areas connected to impulsive buying that are underexplored. Figure 2. Overlay Visualization The researchers are intrigued with the issue of impulsive buying and scarcity cues, live commerce and FOMO tendencies as determinants, which we find missing in the recent literature. The scarcity cues are indicators or information that suggest that something is restricted or difficult to get (Broeder & Wentink. This scarcity cues can provoke FOMO tendencies because someone may believe they have to instantly take action to acquire it before it is too late or runs out (Gullu & Serin, 2. On the other side, a shortage of resources is generated by a demand-supply mismatch, which generates scarcity (Kristofferson et al. , 2. According to Rahmawati & PrimantoAos . , scarcity cues have emerged as an indicator of impulsive buying. yNelik et al. further add the tendency for FOMO to lead to impulsive buying. Consumers are able to interact with sellers through the live commerce function. Additionally, customers will be aroused in their cognitive and emotional states, leading to purchase activities (Usadi et al. Zhang et al. , 2. Shopping impulsively, unplanned shopping behaviour, limited thinking, and demands to meet wishes promptly are prone to giving rise to post-purchase regret (Barek & Gharbi, 2. Consumers must consider all sorts of risks that will come Is Impulsive Buying for Muslim Fashion Products Invariably Followed by Post-purchase Regret? The Role of S-O-R Theory after a purchase so that they do not end up regretting it (Kumar et al. , 2. This research becomes more fascinating with the introduction of indicators of religion as a moderator. Alfi & Yusuf . assert that religiosity relates to the level of an individualAos connection to their faith. The more someone understands their faith, the more profound the effect on their daily actions. Andariesta et al. propose that Muslim consumers think of spirituality in their consumption behaviour. Hypothesis Development Scarcity Cues. FoMO Tendencies. Impulsive Buying As stated by Jha et al. , scarcity cues are a potential determinant of unplanned purchases since the existence of scarcity cues may result in the feeling of urgency towards owning a product. Moreover. Muslim fashion products typically undertake promotional events for consumers (Nasution, 2. As a result, the resultant scarcity is also considered to induce emotional activity such as anticipation of regret. Feelings of scarcity tied to a product will cause the minds of customers to be prepared to sacrifice more resources to get a product advertised with the cues (Kristofferson et al. , 2. A product that has limited availability on the market will call for decisions. In fact, scarcity cues itself might activate FoMO, because the fear of missing an opportunity would lead to a desire to acquire the product quickly . Nelik et al. The scarcity cues also likely raise customerAos perceived value of a product or service, stimulate consumers to increase purchase intensity, limit searches related to other items, and produce fulfilment. The enthusiasm felt by prospective consumers has a positive impact on impulsive buying behaviour (Secapramana et al. , 2. Broeder & Wentink . then claim that restricted purchasing time and flash sales in e-commerce would immediately result in impulsive purchases. When the product has won their trust, the sensation of instantly desiring to buy it will occur by itself (Suhardi et al. , 2. Furthermore, enthusiasm can be developed when the desired product is well reviewed by online vendors (Dahmiri et al. , 2. Kristofferson et al. state that limited quantity of products and time will lead to the formation of impulsive buying behaviour. They also identify scarcity cues as a factor sustaining FoMO and fostering impulsive buying behaviour. It is evident that scarcity cues can cause FoMO tendencies (Suhardi et al. , 2023. Zhang et al. , 2. , as well as give rise to impulsive buying (Hajar & Musadik, 2021. et al. , 2021. Rahmawati & Primanto, 2. Previous research has also established that FoMO is a predictor of impulsive buying (Ahmed et al. , 2020. yNelik et al. Based on the above, the hypotheses to be tested are: H1: Scarcity cues are positively related to FoMO in Muslim fashion. H2: Scarcity cues are positively related to impulsive buying in Muslim fashion. H3: FoMO tendencies have a positive relationship to impulsive buying in Muslim Fashion. Journal of Islamic Monetary Economics and Finance. Vol. Number 3, 2025 Live Commerce. Impulsive Buying According to Ming et al. , live commerce will induce viewers to make impulsive buying of the products that are being offered. The live commerce feature becomes transactional booster in e-commerce platform. The feature enables realtime interactions between viewers and broadcasters, which can affect customer attitudes and behaviors (Wang et al. , 2. This is because the involvement and delivery of the product by the broadcaster might influence feelings . of those watching, resulting in unintended behavior by them. These emotions develop because, with live commerce, viewers may not only acquire complete information about the products being promoted, but they are also able to interact directly with the host so that they better grasp the purpose and value of the products being marketed. Many e-commerce platforms offer Muslim items live because live commerce can enhance revenue from sales (Ardiyanti. This gradually builds the viewerAos faith in the products being advertised. Ming et al. and Zhang et al. , have shown that direct sales can lead to impulsive buying. Accordingly, the research hypothesis is: H4: Live Commerce has a positive relationship with impulsive buying of Muslim Fashion. Impulsive Buying. Post-Buying Regret. Religiosity Impulsive buying is shopping behavior that occurs when there is a resilient, deep, and unexpected desire to acquire something instantly (Rook & Fisher, 1. This action is preceded by feelings of animosity and tends to neglect the impact or repercussions that will be achieved subsequently (Ardiyanti, 2. Buying with a limited time to consider the worth of an item, unexpected purchasing behavior, minimal contemplation, and expectations to rapidly fulfill oneAos desires are prone to cause post-purchase regret (Secapramana et al. , 2. Post-buying regret can occur due to factors such as hesitation, lack of consideration, impulsiveness, pessimism, being overly bold to take risks, being too careful, enjoying comparing oneself with others, and being sensitive to criticism and suggestions from people (Kumar et al. , 2020. Lee & Cotte, 2. As Kumar et al. and yNelik et al. note, impulsive buying has a positive and substantial hyperlink with postpurchase regret. therefore, the greater the impulsive buying, the higher the postpurchase regret. According to Glock & Stark . , religiosity is societal behavior that is totally molded by belief in the supranatural or supernatural world, particularly supra-empirical reality. The more someone understands their religious beliefs, the bigger the effect on their everyday actions. Alfi & Yusuf . advocate that Muslim consumers strengthen their spirituality to manage consumption behavior. According to Rahayu . , religion has an adverse effect on the desire to acquire an object. In a similar vein. Maryati et al. note that an intense comprehension of behaviors based on religiosity has a significant impact on individual behavior, notably in decision-making. Impulsive buying online is a negative behaviour of a person that happens without forethought and can lead to waste and unnecessary purchases. Islam enlightens modesty (Alfi & Yusuf, 2. , not being excessive or wasteful and Is Impulsive Buying for Muslim Fashion Products Invariably Followed by Post-purchase Regret? The Role of S-O-R Theory encouraging simplicity in consumption but also not stopping people from enjoying the gifts that Allah SWT has given (Maryati et al. , 2020. Rahayu, 2. This religiosity can be applied as one of the reasons for someone to make purchase selections so that they do not end up regretting them, especially for Muslim fashion Zeelenberg & Pieters . claim that there are two things in the process of the creation of regret: regret that occurs if there is no or inadequate consideration, and regret that arises if there is too much consideration for the object acquired. So, we posit that religion is a self-controlling component in the relationship between impulsive buying and post-purchasing regret. Based on the reasoning above, the hypotheses are: H5: Impulsive buying behaviors are positively connected to post-purchase regret H6: Religiosity is adversely related to post-purchase regret H7: Religiosity could decrease the connection between impulsive buying and post-purchase regret i. METHODOLOGY Data This research focuses on Muslim customers in Indonesia. A convenience sampling approach is chosen for research purposes. The convenience sampling strategy necessitates the inclusion of only those who are available in the research sample (Andrade, 2. Then, 323 customers answered the survey. nevertheless, only 312 questionnaires are used following the examination of their accuracy. A total of 11 respondents are not included because they have not purchased Muslim fashion products, but they could have bought other products. Several scale statements are drawn from prior studies: the scarcity message scale comprises four statements based on Broeder & WentinkAos . , and Li et al. the FOMO tendency includes three statements from yNelik et al. , and Gullu & Serin . the live commerce scale consists of six statements based on Sharabati et al. , and Zhang et al. the impulsive buying scale features four statements from Nurohman & Aziz . , and Rizki et al. the postbuying regret scale contains four statements from Lee & Cotte . and the religiosity scale contains five statements based on Alfi & Yusuf . and Glock & Stark . These are presented in Table 1. The questionnaire link was distributed through the WhatApps group, and we additionally used sponsored Instagram for the same purpose. Sponsored Instagram is thought to be a viable advertising technique according to customer desires and aims (Amira & Nurhayati, 2. The survey was conducted from October to December 2023. Our respondents found it comfortable to complete the questionnaire in digital format with the Google Form link. Journal of Islamic Monetary Economics and Finance. Vol. Number 3, 2025 Table 1.

BartlettAos Sphericity test produced NA = 992. 009, df = 181, and p < 0. 001, further substantiating the adequacy of the analytical instruments examined in the study. The standardized factor loadings for all measuring items reach 0. 7, showing that the items successfully reflect the properties of their associated latent variables. The reliability is examined by calculating the CronbachAos alpha coefficient and composite reliability (CR) to quantify the internal consistency of the scale. The results (Table . demonstrate that the Cronbach coefficients for all latent variables exceed 0. 7 threshold, and the CR values likewise exceed the recognized requirement of 0. 7, signaling substantial measurement reliability (Hair et al. , 2.

As for the moderating role of religiosity, the result supports our hypothesis that religiosity weakens the relationship between impulsive buying and post-purchase regret (IB>R>PPR has P 0. Robustness Test In this study, a non - linear approach is used to assess the extent to which the constructs in the model conform to theoretical expectations (Sarstedt et al. , 2. While theoretical models generally imply linear relationships between constructs, real-world relationships may not always follow this assumption. In statistical terms, a non-linear relationship means that the strength of the relationship between two constructs is influenced by the specific value of the exogenous construct and the rate of change in it. Based on the quadratic effect results, all P values AUAUfor the paths are higher than 0. 05, indicating that the interactions are not significant. This indicates that the linear effect of the pathway remains strong and reliable in accordance with Sarstedt et al. Table 6.

Vol. Number 3, 2025 Discussions Overall, the SOR model developed by Hovland et al. effectively predicts impulsive buying. This research shows that scarcity cues can activate FoMO because a person feels that they must immediately seize the opportunity before it is too late or a product is sold out . Nelik et al. , 2019. Dahmiri et al. , 2. It can be asserted that when consumers believe that the product offered is restricted, it stimulates their urge to acquire it instantly. In line with prior studies . Nelik et al. Suhardi et al. , 2023. Zhang et al. , 2. H1 is supported. Online e-commerce buying offers many various items, including Muslim fashion, which is the current trend (Izza, 2. Muslim garments are popular for Indonesian Muslims (Nugraha et al. , 2. Muslim consumers can become worried if they lose the opportunity of buying fashionable items. Therefore, the increased amount of scarcity cues could set off a worry. Then, from the statistical results. SC has a positive effect on IB, in line with previous research on impulsive buying behaviours (Dahmiri et al. , 2023. Hajar & Musadik, 2021. Kristofferson et al. , 2017. Li et al. , 2021. Nasution, 2022. Rahmawati & Primanto, 2. This finding implies that scarcity cues can influence impulsive buying because its creates fear and anxiety in customers that they would miss the opportunity to acquire the goods if they fail to purchase them immediately (Dahmiri et al. , 2. Consumers tend to feel threatened when they notice messages of limited product availability within a given period of time, and they will take impulsive action to acquire the products so as not to risk missing out. a result.
