O Prophet, urge on the believers to fight. If there be twenty of you, patient men, they will overcome two hundred; if there be a hundred of you, they will overcome a thousand unbelievers, for they are a people who understand not. 65 God has now lightened your burden, for He knows that there is weakness in you. If there are a hundred of you who are steadfast, they will overcome two hundred; and if there are a thousand of you, they will overcome two thousand by God's will. God 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 there not been a previous decree from Allah, a stern punishment would have afflicted you for what you have taken. 68 But (now) enjoy what ye took in war, lawful and good: but fear Allah: for Allah is Oft-forgiving, Most Merciful. 69
