O Prophet (Muhammad SAW)! Urge the believers to fight. If there are twenty steadfast persons amongst you, they will overcome two hundred, and if there be a hundred steadfast persons they will overcome a thousand of those who disbelieve, because they (the disbelievers) are people who do not understand. 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 that a writ had already gone forth from Allah, there would surely have touched you a mighty torment for that which ye took 68 Eat of what you have taken as booty, such as is lawful and good; and fear you God; surely God is All-forgiving, All-compassionate. 69
