Prophet, urge the believers to fight; if there are twenty of you who are steadfast, they will overcome two hundred, and if there are a hundred of you, they will overcome a thousand of those who deny the truth, for they are devoid of understanding. 65 Now hath Allah lightened your burden, for He knoweth that there is weakness in you. So if there be of you a steadfast hundred they shall overcome two hundred, and if there be of you a thousand (steadfast) they shall overcome two thousand by permission of Allah. Allah is with the steadfast. 66 It is not right for a Prophet to keep captives unless he has battled strenuously in the land. You desire the gain of this world, while God desires for you the Hereafter -- God is mighty and wise. 67 Had Allah not pre-destined a matter then, O Muslims, a terrible punishment would have come upon you due to the ransom you took from the disbelievers. 68 Now enjoy what ye have won, as lawful and good, and keep your duty to Allah. Lo! Allah is Forgiving, Merciful. 69
