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 So, fight them till all opposition ends, and obedience is wholly God's. If they desist then verily God sees all they do. 39 but if they turn away, know that Allah is your guardian, (He is) the best Guardian and the best Giver of victory. 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 (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 to you in your dream as few; and if He had shown them to you as many you would certainly have become weak-hearted and you would have disputed about the matter, but Allah saved (you); surely He is the Knower of what is in the breasts. 43 And when He showed them to you, when you met, as few in your eyes and He made you to appear little in their eyes, in order that Allah might bring about a matter which was to be done, and to Allah are all affairs returned. 44
