[O Prophet!] Tell the unbelievers that if they desist from evil, their past shall be forgiven and if they revert to their past ways, then it is well known what happened with the people of the past. 38 And fight against them until there be no temptations and their obedience be wholly unto Allah. So if they desist, then verily Allah is the Beholder of that which they do. 39 But if they are obstinate, know that God is your helper and protector: How excellent a helper, and how excellent a protector is He! 40 ۞ And know that anything you obtain of war booty - then indeed, for Allah is one fifth of it and for the Messenger and for [his] near relatives and the orphans, the needy, and the [stranded] traveler, if you have believed in Allah and in that which We sent down to Our Servant on the day of criterion - the day when the two armies met. And Allah, over all things, is competent. 41 (And remember) when you (the Muslim army) were on the near side of the valley, and they on the farther side, and the caravan on the ground lower than you. Even if you had made a mutual appointment to meet, you would certainly have failed in the appointment, but (you met) that Allah might accomplish a matter already ordained (in His Knowledge); so that those who were to be destroyed (for their rejecting the Faith) might be destroyed after a clear evidence, and those who were to live (i.e. believers) might live after a clear evidence. And surely, Allah is All-Hearer, All-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 When God showed you them in your eyes as few, when you encountered, and made you few in their eyes, that God might determine a matter that was done; and unto God all matters are returned. 44
