This study aims to explore the meaning of pocket money in shaping the lifestyle construction of students (santri) at Pondok Pesantren Sains Salman Assalam, from the perspective of Islamic economics. The unique consumption patterns of students within the pesantren environment are examined to understand how pocket money functions not merely as a medium of exchange but also as a determinant of consumption behavior, value preferences, and identity formation. Employing a qualitative approach with an interpretative phenomenological method, the research involves students as primary subjects who directly experience the dynamics of pocket money usage in daily life. Data collection techniques include in-depth interviews, participatory observation, and documentation. The findings reveal that pocket money carries various symbolic meanings, ranging from a form of parental affection, a medium for social status affirmation, to a means of fostering financial independence and management based on Islamic principles. Students' lifestyles are shaped by a combination of pesantren values, peer influence, and access to pocket money, resulting in a consumption pattern that is moderate, selective, and sometimes contradictory to the simplicity values taught. The study concludes that strengthening Islamic financial literacy within pesantren is essential for character development. It is recommended that pesantren authorities and families actively participate in educating students about prudent and value-based financial management.
