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 God has lightened your burden as He knows you are weak: So, if there are a hundred men of firm determination among you, they will vanquish two hundred; and if there are a thousand of you they will vanquish two thousand by the will of God, for God is with those who are determined. 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
