The Friday night Surah Yasin recitation tradition is one of the religious activities that continues to be preserved by the community of Jorong Simpang Ampek, Sitanang Village, Ampek Nagari District, Agam Regency, West Sumatra. This tradition serves not only as a form of collective worship but also as a medium for strengthening religious values, social solidarity, and preserving Islamic cultural heritage passed down through generations. This article aims to describe the process of internalizing religious values through the participation of Community Service Program (Kuliah Kerja Nyata/KKN) students in the Surah Yasin recitation activity with the local community. The activity was conducted on June 18, 2026, using a participatory approach by involving students directly in the complete recitation session, followed by social interaction with community members. Data were collected through participatory observation, interviews with ten informants, and documentation. The findings indicate that students' participation in the Yasin recitation provided contextual learning experiences regarding the community's religious and social life while strengthening their understanding of religious values, togetherness, social awareness, and Islamic brotherhood reflected in the tradition. Furthermore, the interaction between students and community members after the activity fostered closer social relationships and enhanced students' appreciation of local wisdom. Therefore, the participation of KKN students in the Surah Yasin recitation contributes to strengthening religious values while supporting the preservation of local Islamic traditions as an integral part of community engagement based on local wisdom.
