A "da'i" is an individual who invites others to understand and embrace the teachings of a particular faith, often within the context of Islam. The term is derived from the Arabic word "da'wah," which means "invitation." Da'is play a crucial role in spreading religious knowledge and fostering dialogue about spiritual beliefs. In many communities, da'is engage in various activities, such as giving lectures, distributing literature, and participating in interfaith discussions. Their goal is to educate others about the principles of their faith and encourage a deeper understanding of religion and spirituality.
