[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 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 You were on the nearer side of the valley, and they were on the farther side, and the caravan was below you. Had you wished to set a time by mutual agreement, you would certainly have disagreed on the timing. However, the encounter took place, so that God might settle a matter which had already been ordained, so that he who was to perish might perish after clear evidence of the truth, and he who was to live might live in clear evidence of the truth. Surely, God is all hearing and all-knowing. 42 Remember in thy dream Allah showed them to thee as few: if He had shown them to thee as many, ye would surely have been discouraged, and ye would surely have disputed in (your) decision; but Allah saved (you): for He knoweth well the (secrets) of (all) hearts. 43 And remember when ye met, He showed them to you as few in your eyes, and He made you appear as contemptible in their eyes: that Allah might accomplish a matter already enacted. For to Allah do all questions go back (for decision). 44
