This community service activity was motivated by the absence of a routine communal recitation of Surah Al-Kahfi on Friday nights at Nurul Ihsan Mosque, Jorong Lambeh, while religious activities at the mosque were still predominantly focused on congregational prayers. This activity aimedtoestablisharoutine of reciting Surah Al-Kahfievery Fridaynight through communal recitation. The activity employed a mentoring approach involving the congregation of Nurul Ihsan Mosque, Jorong Lambeh, Nagari Ampek Koto, Palembayan District, Agam Regency, during June–July 2026. The activity was conducted five times after Maghrib prayer and before Isha prayer, involving male adults, women, and adolescents. Data were collected through observation and documentation and analyzed descriptively and qualitatively by examining the implementation of the activity and the congregation's participation in each meeting. The results showed that the recitation of Surah Al-Kahfi was conducted routinely according to the schedule, with attendance ranging from 4 to 10 participants in each meeting. During the program, there was a development in the congregation's involvement, from initially listening or reading individually at a slower pace to gradually participating by taking turns using the mosque's loudspeaker. The activity contributed to establishing a new religious activity within the mosque and provided the congregation with an initial experience of participating in communal Surah Al-Kahfi recitation.
