The mosque has engaged in religious calling and propaganda through various religious-spiritual, cultural-ritual, social, and political functions.

In this regard, and in order to lay the groundwork for this institution to play a more effective role in the future of society and because of necessity of making correct policy in this field. The future functions of the mosque have been studied by the scenario writing method. In order to draw alternative modes for the future of the mosque's preaching based on its new functions.
Scenarios are the face of the future and their purpose is to describe possible images of complex and different future conditions. In the current research, first, the diversity and historical development of the mosque's functions have been reviewed, then the micro and macro trends affecting the future of the mosque's preaching have been explained and evaluated, and thus the reason for change in the future of the mosque's preaching have been determined. Finally, the "future needs of the people" were identified as the most important driver that has uncertainty, and two scenarios were defined with the focus on the two functions of "social services" and "giving meaning to life" and the scenarios were developed by the method of a collaborative workshop and approved by experts, the subject is described.
