Islamic preachers, also known as da'is, are individuals who promote the teachings of Islam and encourage others to follow its principles. They often deliver sermons, lectures, and educational sessions in mosques or community centers, focusing on the core beliefs of the faith, such as the Quran and the teachings of the Prophet Muhammad. These preachers may come from various backgrounds and can be scholars, community leaders, or volunteers. Their role is to provide guidance on religious practices, moral conduct, and social issues, helping to foster a deeper understanding of Islam among followers and the wider community.
