Justice is one of the important cases of religious belif and social subjects that Divine prophets have been appointed to establish it. Justice has always been taken into account by commentators and sociologists and it has been the infrastructure of important affairs such as freedom, law, and possession. Regarding justice, various definitions have been proposed by experts. Having a query on the verses of Quran, the present paper attempts to explicate that meaning of justice upon which other definitions have been evaluated. Investigation shows that definition of justice, as a description or behavior, depends on an endowment or belonging to which justice is endowed or belonged. Accordingly, justice in Quran includes meanings such as: respecting equality, observing deservingness and aptness, honesty or acting in accordance with reality, holding fair in peace and bringing reconciliation within the divine rules, avoiding extremes, having everything in the appropriate position, observing the real interests and corruptions, and obeying the true laws.
