[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 is no more oppression and all worship is devoted to God alone. And if they desist - behold, God sees all that they do; 39 But if they turn away, then know well that Allah is your Protector - an excellent Protector and an excellent Helper. 40 ۞ Know that, whatever booty you take, the fifth of it is God's, and the Messenger's, and the near kinsman's, and the orphans', and for the needy, and the traveller, if you believe in God and that We sent down upon Our servant on the day of salvation, the day the two hosts encountered; and God is powerful over everything; 41 And when you were encamped on the nearside and they (the unbelievers) on the farther side, with the caravan below, had you made an appointment with them, you would have surely failed to keep it; but Allah sought to accomplish what He had ordained, so that by clear evidence, he who was destined to perish might perish, and he who was destined to live might live. Surely, Allah is Hearing, Knowing. 42 And when Allah made them appear to you in a vision as a small band, had He showed them to you as many, your courage would have failed you and you would have quarreled over the affair. But Allah saved; He knows the inner most thoughts in the chests. 43 And recall what time He shewed them few in your eyes when ye met and lessened you in their eyes in order that Allah might decree an affair already enacted; and unto Allah are all affairs returned. 44
