The research treats of the Arab comparative review of the notion of justice before and after Islam. It, also, gives a linguistic definitions of the term "justice "and its derivations with some idiomatic meanings. Moreover, the research tackles the development of the notion of "justice "before and after Islam and the social conditions that pinpointed the notion at that time.The research indicates that the notion of justice before and after Islam means, for the most, securing the influential men's interests against the poor's .After Islam the norms was entirely different, and the question of "Justice" became God's law which applies to every Muslim whether they are lords or slaves, the rich or the poor, the governors or the governed. The justice, also, applies to every body notably the Prophet Mohammed (God's blessings be upon him). Moreover, it applies to non-Muslims and this feature distinguishes Islam from other religions. Thus, justice from Islamic point of view, is a perfect judicial system which tackles all questions of life, especially, political, economical and social aspects. This viewpoint is one of the basic factors which contributed in spreading Islam among the non-Muslims.
