Permission to fight is (against disbelievers) is given to those (believers), who are fought against, because they (believers) have been wronged, and surely, Allâh is Able to give them victory. (39) Those who have been expelled from their homes unjustly only because they said: "Our Lord is Allâh." - For had it not been that Allâh checks one set of people by means of another, monasteries, churches, synagogues, and mosques, wherein the Name of Allâh is mentioned much would surely have been pulled down. Verily, Allâh will help those who help His (Cause). Truly, Allâh is All-Strong, All-Mighty. (40) Those (Muslim rulers) who, if We give them power in the land, (they) enjoin Iqamat-as-Salât.[] [i.e. to perform the five compulsory congregational Salât (prayers) (the males in mosques)], to pay the Zakât and they enjoin Al-Ma'rûf (i.e. Islâmic Monotheism and all that Islâm orders one to do), and forbid Al-Munkar (i.e. disbelief, polytheism and all that Islâm has forbidden) [i.e. they make the Qur'ân as the law of their country in all the spheres of life]. And with Allâh rests the end of (all) matters (of creatures). (41) And if they belie you (O Muhammad SAW), so did belie before them, the people of Nûh (Noah), 'Ad and Thamûd (their Prophets). (42) And the people of Ibrâhim (Abraham) and the people of Lut (Lot), (43) And the dwellers of Madyan (Midian); and belied was Mûsa (Moses), But I granted respite to the disbelievers for a while, then I seized them, and how (terrible) was My Punishment (against their wrong-doing)! (44) And many a township did We destroy while it was given to wrong-doing, so that it lies in ruins (up to this day), and (many) a deserted well and lofty castle! (45) Have they not travelled through the land, and have they hearts wherewith to understand and ears wherewith to hear? Verily, it is not the eyes that grow blind, but it is the hearts which are in the breasts that grow blind. (46)
