The community is a partner as well as a target in the process of da'wah activities who have great hopes for the da'wah as the executor of the da'wah, although not all of the hopes of the community are in the dai, but the weaknesses and shortcomings that the dai has as an ordinary human being are not a reason for the dai to continue to introspect himself to be better. This is because the preacher must realize that he is a role model for the people, who will be a source of reference for the people in solving religious and social problems, because personality integrity is an important factor that can support the success of da'wah.
