This study aims to investigate the effectiveness of the Mau'idzah Hasanah da'wah
delivered by KH. Bahruddin Abdullah through Islamic studies at the Husnul Khatimah
Grand Mosque in Kotabaru District. This research tries to explore the factors that influence
the success of Mau'idzah Hasanah's da'wah and its impact on the local community.
This research was conducted based on increasing public interest and participation in
Islamic studies delivered by KH. Bahruddin Abdullah. Previous research has shown an
increase in the number of recitation participants after using the Mau'idzah Hasanah da'wah
approach.
The benefit of this research is to provide deeper insight into the effectiveness of
Mau'idzah Hasanah's da'wah as a means of communication and delivery of religious
messages. The results of this study are expected to provide a better understanding of the
influence of Mau'idzah Hasanah's preaching on the local community, including in increasing
their participation and involvement in religious activities. It is hoped that the results of this
research can serve as a reference for da'wah institutions and the community in utilizing
effective da'wah approaches to promote better understanding of religion and increase public
morality.
