Say to those who have disbelieved, if they cease (from disbelief) their past will be forgiven. But if they return (thereto), then the examples of those (punished) before them have already preceded (as a warning). 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 but if they turn away, know that God is your Protector; the Best of Protectors and the Best of Helpers! 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 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
