The implementation of the night Qur'an learning movement at Al-Faizin Mosque, Sungai Puar Hamlet, Sungai Puar Village, Palembayan District, Agam Regency, encountered several challenges, including inconsistent attendance of children and the limited application of tajwid rules despite their fluency in reading the Qur'an. This community service program aimed to revitalize the night Qur'an learning movement through tahsin assistance to improve the quality of Qur'anic recitation among elementary school children. The program employed a Participatory Action Research (PAR) approach involving the stages of initial observation, problem identification, action planning, implementation, evaluation, and reflection. The activity was conducted from 3–16 June 2026 involving 5–10 children in grades I–V of elementary school, four students of the Islamic Education Study Program, and the local Qur'an teacher. Data were collected through observation, interviews, documentation, and direct evaluation of participants' recitation. The results indicated improvements in the accuracy of makharijul huruf, the application of basic tajwid rules such as mad, izhar, ikhfa, and idgham, and increased confidence among children when reciting the Qur'an individually. The program also supported the Qur'an teacher in providing more intensive guidance through individualized mentoring. This community service contributes to strengthening the quality of existing night Qur'an learning activities without changing the established learning system. Therefore, tahsin assistance can serve as an effective strategy for improving Qur'anic literacy and supporting the sustainability of mosque-based religious education in the community.
