Moreover, if all the policies are claimed as God's desire to make society directly receive them as that was happened in medieval Europe, where all leaders claimed themselves as the representatives of God. That action caused a dispute between the leaders and their society that was happened in several centuries. As Islam has seen a leader as a human being who is not in spite of mistakes those should be rectified by society, this paper will clearly describe the things those should be heeded by the leaders so that the society will not feel disadvantaged.
