[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 Fight them, till there is no persecution and the religion is God's entirely; then if they give over, surely God sees the things they do; 39 If the (unbelievers) turn away from the faith, God is you (believers) best Guardian and best Helper. 40 ۞ And know that whatever ye take as spoils of war, lo! a fifth thereof is for Allah, and for the messenger and for the kinsman (who hath need) and orphans and the needy and the wayfarer, if ye believe in Allah and that which We revealed unto Our slave on the Day of Discrimination, the day when the two armies met. And Allah is Able to do all things. 41 (That day) when you were at one end of the valley, (the unbelievers) at the other, and the caravan below you (on the lowland by the coast), you would surely have declined to fight if (the Makkans) had offered you battle. (But the battle did take place) that God may end the matter which had been accomplished, so that he who had to die may perish after a clear demonstration, and he who had to live may survive in the light of positive proof, for God hears all and knows everything. 42 When Allah showed them unto thee (O Muhammad) in thy dream as few in number, and if He had shown them to thee as many, ye (Muslims) would have faltered and would have quarrelled over the affair. But Allah saved (you). Lo! He knoweth what is in the breasts (of men). 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
