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, 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 an ordinance of Allah which had gone before, an awful doom had come upon you on account of what ye took. 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
