[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 turn away, then know well that Allah is your Protector - an excellent Protector and an excellent Helper. 40 ۞ Know that one-fifth of your battle gains belongs to God and the Messenger, to his close relatives and orphans, to the needy and travellers, if you believe in God and the revelation We sent down to Our servant on the Decisive Day, the day when the two forces met. God has power over all things. 41 And recall what time ye were on the hither side and they were on the yonder side and the caravan below you. And if ye had mutually appointed ye would surely have failed the appointment. But the action was brought about in order that Allah may decree an affair already enacted, so that he who was to perish should perish after an evidence, and he who was to remain alive may remain alive after an evidence. And verily Allah is Hearing, Knowing. 42 God showed them to you in your dream as small in number. If He had shown them to you as many, you would have lost heart and disputed about the matter; but God saved you. He has full knowledge of what is in the human heart. 43 And when at the time of fighting He made the disbelievers seem few to you, and you as few in their sight, in order for Allah to conclude the matter that must be done; and towards Allah is the return of all matters. 44
