<![CDATA[ABSTRACT Introduction: The consumption behavior of Muslims is normatively regulated by the principles of halal (permissible), balance (wasathiyah), and prohibition of excess (israf) as emphasized in the Qur'an, Surah Al-A'raf, verse 31. Islamic boarding schools, as the oldest Islamic educational institutions in Indonesia, numbering more than 42 thousand institutions, ideally become social spaces that foster simple and worshipful consumption patterns among students. However, initial observations at the Zainul Hasan Genggong Islamic Boarding School indicate a gap between the normative regulations of Islamic boarding schools and the actual consumption practices of students. This article aims to explain the background, urgency, and novelty of research on the gap between Qur'anic values and students' consumption behavior. Methods: This article is compiled based on a literature review (state of the art) of twelve previous studies on the consumption behavior of Islamic boarding school students and Muslims as well as preliminary interview data with six male and female Islamic boarding school informants at the Zainul Hasan Genggong Islamic Boarding School, Probolinggo Regency, which is strengthened by secondary data from the Indonesian Ministry of Religion and the State of the Global Islamic Economy Report 2024/2025. Results: Initial research indicates that despite strict regulations in Islamic boarding schools, including boarding house systems, closed cooperatives, and daily spending restrictions, students' consumption practices continue to exhibit excessive spending on food, appearance, and personal care, including through online shopping. Previous research has also failed to produce a model of consumption behavior explicitly based on Quranic values and empirically tested within Islamic boarding schools. Conclusion and suggestion: A consistent gap was found between the normative Qur'anic values taught in Islamic boarding schools and the actual consumption behavior of Islamic boarding school students, as well as the absence of an operational Qur'anic value-based consumption model in previous literature. This situation emphasizes the urgency of further research to formulate a model of Islamic boarding school student consumption behavior based on Qur'anic values that can serve as a theoretical and practical reference for Islamic boarding school management.]]>
