Also, the legitimacy of laws and government comes from the sovereign will of the people, and governments guarantee the rights and freedom of the people.In fact, maintaining and respecting such mutual rights is necessary for the individual and the society. Because it is only in the shadow of fulfilling duties and fulfilling the right that the government and the individual can grow. In the Islamic system, there is a direct relationship between the people and the absolute sovereignty of God, and the people have been granted the right to self-determination, and the people have accepted this religious basis.
