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 against them until the mischief ends and the way prescribed by Allah - the whole of it -prevail Then, if they give up mischief, surely Allah sees what they do. 39 If the (unbelievers) turn away from the faith, God is you (believers) best Guardian and best 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 Remember ye were on the hither side of the valley, and they on the farther side, and the caravan on lower ground than ye. Even if ye had made a mutual appointment to meet, ye would certainly have failed in the appointment: But (thus ye met), that Allah might accomplish a matter already enacted; that those who died might die after a clear Sign (had been given), and those who lived might live after a Clear Sign (had been given). And verily Allah is He Who heareth and knoweth (all things). 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 so, when you met in battle, He made them appear as few in your eyes - just as He made you appear as of little account in their eyes - so that God might accomplish a thing [which He willed] to be done: for all things go back to God [as their source]. 44
