Religion is found on earth with the existence of humans being an innate mountainous matter, in order to regulate the life of the individual, family, society and the state, so Islamic law was revealed to regulate the life of the Muslim community, and even non-Muslims who obtain Islamic sciences regardless of the worship aspect. Islamic law is involved in all aspects of life at the individual and society level through its institutions, which are the mosque, the Husseiniya, the school, religious centers, hospice, and others. Our modest study reviewed the social role of the Islamic religion and the mechanism of that role through social institutions to maintain societal stability, at the individual and societal level.
