O Prophet, urge the faithful to fight. If there are twenty among you with determination they will vanquish two hundred; and if there are a hundred then they will vanquish a thousand unbelievers, for they are people devoid of understanding. 65 For the time being, [however,] God has lightened your burden, for He knows that you are weak: and so, if there be one hundred of you who are patient in adversity, they should [be able to]' overcome two hundred; and if there be one thousand of you, they should [be able to] overcome two thousand by God's leave: for God is with those who are patient in adversity. 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 it not been for a previous ordainment from Allah, a severe penalty would have reached you for the (ransom) that ye took. 68 Use what you have acquired (from the battle) as your own good, lawful property. Have fear of God; He is All-forgiving and All-merciful. 69
