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 Were it not for an ordinance from Allah that had already gone forth, surely there would have befallen you a great chastisement for what you had taken to. 68 Now enjoy what ye have won, as lawful and good, and keep your duty to Allah. Lo! Allah is Forgiving, Merciful. 69
