The actions and competencies of da’i in Muallaf Village, Sangbua, South Sulawesi are investigated in this study. Because practically all of the population of this village are converts to Islam, tolerant, and open to change, it was chosen as the subject of inquiry. They are still prone to shocks to religious thinking as well as economic temptations as converts. The study used a sociological-anthropological approach using qualitative methodologies. The information was gathered through in-depth interviews and analyzed utilizing the theory of da’wah competency. Islamization, the economy, and social dynamics were identified to be three essential factors in this study. The da’i, also known as mosque imams, have a rudimentary understanding of how to preach effectively to the majority of Protestant Christians. Competence produced maximum results, resulting in the conversion of the bulk of Christians to Islam. Not only is he preaching by vocally imparting Islamic beliefs, but he is also actively involved in offering economic support. Form regular monthly meetings with all farmers/planters to solve agricultural and plantation difficulties. Finally, the socio-religious dynamics are in accord, as seen by the reduction of religious conflicts, the acceptance of inter-faith marriage, and the rejection of religious coercion. Mentoring is an important item which should be followed up on on a regular basis, mostly to develop religious insights that are friendly but adaptable to community changes while still retaining local traditions.
