Permission (to fight) is given to those upon whom war is made because they are oppressed, and most surely Allah is well able to assist them; / Those who have been expelled from their homes without a just cause except that they say: Our Lord is Allah. And had there not been Allah's repelling some people by others, certainly there would have been pulled down cloisters and churches and synagogues and mosques in which Allah's name is much remembered; and surely Allah will help him who helps His cause; most surely Allah is Strong, Mighty. quran quran
