Mosques can function as religious institutions and community-based economic organizations when commercial activities are governed by Islamic values and directed toward social objectives. Therefore, this study aims to examines how Misbahus Sunnah Mosque in Bogor, Indonesia, integrates halal-oriented commercial services, social reinvestment, and socio-cultural regeneration within a mosque-centred Islamic Social Enterprise model. The study procedures were carried out using a qualitative single instrumental case approach supported by participant observation, semi-structured interviews, and document analysis. A total of 13 key informants were selected purposively, comprising a foundation supervisor, an amil, 2 program teachers, 2 donors, a halal muamalah business actor, the Head of RW 02, and 5 successful program beneficiaries. Data were then organized using NVivo 12 and analyzed through reflexive thematic analysis and source triangulation. The results showed 4 interconnected dimensions, including revenue governance, a halal service ecosystem, social reinvestment, and the Da’i-preneur regeneration pathway. Diponegoro Stable contributed approximately 65% of enterprise income, while property services, ballroom rental, and event-organizer activities contributed the remaining 35%. The foundation reinvested available income in Qur’anic education, elderly empowerment, social assistance, mosque development, and religious-entrepreneurial education. In addition, institutional sustainability depended on professional service management, separate financial recording, transparent allocation, stakeholder trust, and accountable oversight. The study extended Islamic Social Enterprise analysis by explaining how halal and tayyib principles, productive assets, and Maqasid al-Shari’ah were operationalized within an integrated mosque empowerment ecosystem. As a single-case study, these results offered analytical transferability rather than statistical generalization.
