"As in the case of individuals, so inter-state relationship, war could only be waged for the sake of justice, truth, law and preservation of human society. The central theme behind the causes of wars, as spelt out by the holy Quran, was the cause of Allah. This cause manifested itself in different shapes and forms at different stages in the history of Islam. In the pursuit of this cause, the Muslims were first granted the permission to fight but were later commanded to fight in the Way of God as a matter of religious obligation and duty. The first Quranic revelation of the subject that granted the Muslims the permission to fight, read, "To those against war is made, permission is given (to fight) because they are wronged;—and verily, Allah is most Powerful for their aid. (They are) those who have been expelled from their homes in defiance of right,—(for no cause) except that they say, 'Our lord is Allah." Deliberating on the rationale behind the grant of the permission, the Book ruled, "Did not Allah check one set of people by means of another, there would surely have been pulled down monasteries, churches, synagogues and mosques in which the name of Allah is commemorated in abundant measure." At another occasion, the Holy Quran said, "Every time the kindle the fire of war, Allah doth extinguish it; but they (ever) strive to do mischief on earth. And Allah loveth not those who do mischief." What expectations did Almighty Allah place on that 'set of people' with whose help He planned to check the other? "(They are) those," the Book claims, "who, if we establish them in the land, establish regular prayer and give regular charity, enjoin the right and forbid wrong." A few months after the grant of the permission to fight in self-defence, came the divine command making war a religious compulsion and obligation. "Fight in the cause of Allah," it said, "those who fight you but do not transgress limits; for Allah loveth not transgressors." This revelation introduced new elements to the permissible causes of war. Fighting was to be in the cause of Allah. It was to be undertaken only against those who fought the Muslims first. During the conduct of war, the limits specified by God were not to be transgressed; those who did so were to incur divine displeasure."
