This study aims to determine the effect of the socialization of zakat, infaq, alms and endowments (ZISWAF) on public awareness, as well as the intermediary function of mosques in East Luwu Regency in the management of ZISWAF. The method used in this research is mix methods, with a sequential explanatory model. Samples obtained were 49 people and 6 community leaders as informants. The results of this study indicate that the socialization variable has a significant effect on public awareness. Thus, this proves that the Al-Muhajirin Mosque, Nurul Yaqin Grand Mosque and the Ibnu Taimiyah Mosque implement the intermediation function of managing their ZISWAF funds by enlivening the mosque through conducting routine programs, teaching TPA and mutual cooperation. However, the application of the intermediation function is still considered to be less than optimal, therefore revitalization of the intermediation function is needed so that the function of the mosque during the time of the Prophet can be carried out again.
