(8:66) 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. (8:67) It is not for a prophet to have captives [of war] until he inflicts a massacre [upon Allah `s enemies] in the land. Some Muslims desire the commodities of this world, but Allah desires [for you] the Hereafter. And Allah is Exalted in Might and Wise. (8:68) If not for a decree from Allah that preceded, you would have been touched for what you took by a great punishment. (8:69) So consume what you have taken of war booty [as being] lawful and good, and fear Allah. Indeed, Allah is Forgiving and Merciful. (8:70) O Prophet, say to whoever is in your hands of the captives, "If Allah knows [any] good in your hearts, He will give you [something] better than what was taken from you, and He will forgive you; and Allah is Forgiving and Merciful." (8:71) But if they intend to betray you - then they have already betrayed Allah before, and He empowered [you] over them. And Allah is Knowing and Wise. (8:72) Indeed, those who have believed and emigrated and fought with their wealth and lives in the cause of Allah and those who gave shelter and aided - they are allies of one another. But those who believed and did not emigrate - for you there is no guardianship of them until they emigrate. And if they seek help of you for the religion, then you must help, except against a people between yourselves and whom is a treaty. And Allah is Seeing of what you do.
