There are many definitions of justice in various Islamic sources and the opinions of thinkers. Still, their most important are: "putting everything in its place, giving the right to the rightful, fulfilling the right, and respecting the rights". Justice in Islam has different levels of individual, the system of existence, God, legislation, and social. Islam considers justice as absolute. Among the most important aspects of justice, social, and political aspects have been mentioned. All divine prophets have been sent to realize this principle. The religion of Islam has put the realization of social justice at the top of its goals, and there are many verses about justice. In such a way that Imam Ali (a.s.) calls the Qur'an the speaker of justice. Also, the negative delay that autocracy has had in preventing the flourishing of the ideas of justice in thought, and action, has caused its regressive course from idealism to realism. This theory can be deduced that the increase of autocracy, and insecurity in the political system has led to the stagnation, and limitation of applying the theories of justice, and their practical transfer from idealism to realism. In this research, the dimensions, and indicators of justice in Islam have been compared with Western thought.
