Da’wa fardiyah activity is an effort to invite human beings to behave according to the guidance from Allah in order to achieve khoirul bariyyah, khoirul usroh, and jama ’a. Since the mission of da ’wah is to send a messege from a da’i to the addressees (ma’du), the process of da ’wa has the similarity with the interpersonal communi- cation system. As a discipline, da ’wa cannot be separated from other disciplines as psychology. This will help the actualization of good da ’wa activities.
