Tell those who are bent on denying the truth that if they desist, all that is past shall be forgiven them; but if they revert [to their wrongdoing,] let them remember what happened to the like of them in times gone by. 38 And fight them until no mischief remains and the entire religion is only for Allah; then if they desist, Allah sees all what they do. 39 but if they turn away, know that God is your Protector -- an excellent Protector, an excellent Helper! 40 ۞ And know that whatever you take as war booty, a fifth of that belongs to Allah and His Noble Messenger, and to relatives, and orphans, and the needy, and the traveller – if you have accepted faith in Allah and what We sent down to Our bondman on the decisive day – the day when two armies had met; and Allah is Able to do all things. 41 When ye were on the near bank (of the valley) and they were on the yonder bank, and the caravan was below you (on the coast plain). And had ye trysted to meet one another ye surely would have failed to keep the tryst, but (it happened, as it did, without the forethought of either of you) that Allah might conclude a thing that must be done; that he who perished (on that day) might perish by a clear proof (of His Sovereignty) and he who survived might survive by a clear proof (of His Sovereignty). Lo! Allah in truth is Hearer, Knower. 42 When Allah showed them to you in your dream as few; and if He had shown them to you as many you would certainly have become weak-hearted and you would have disputed about the matter, but Allah saved (you); surely He is the Knower of what is in the breasts. 43 And when He showed them to you, when you met, as few in your eyes and He made you to appear little in their eyes, in order that Allah might bring about a matter which was to be done, and to Allah are all affairs returned. 44
