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 Now, Allah has lightened [the hardship] for you, and He knows that among you is weakness. So if there are from you one hundred [who are] steadfast, they will overcome two hundred. And if there are among you a thousand, they will overcome two thousand by permission of Allah. And 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 it not been for a prior prescription from God, there had afflicted you, for what you took, a mighty chastisement. 68 So eat that which you have obtained - for it is lawful and clean--and fear Allah. Surely Allah is Ever-Forgiving, Most Merciful. 69
