Thai is why a Muslim is not considered to be a perfect believer unless he loves others. And love is expressed through the greeting of peace (, saldm). Hence peace exists when there is compassion in people's hearts for each other. This, in turn, will end every kind of injustice and will play vital role in establishing a just social order. That implies peace without justice has no meaning as the former is not merely absence of violence and existence of calmness. In the same manner justice cannot be established until the atmosphere is calm and serene. Hence, the administration of justice has always been a religious duty in Islam which consists of the application of the principles of shari'ah in the name of Allah. Unfortunately enough, the non-Muslim mind, especially that of the Orientalists, is ignorant, nay, but chooses to be ignorant about the universal fact that Islam succeeded in materializing in history its principles while the world witnessed the greatest ever commonwealth of which peace and justice were the most brilliant hallmarks.
