O Prophet! say unto the captives who are in your hands: if Allah knoweth any good in your hearts He will give you better than that which hath been taken away from you, and shall forgive you; and Allah is Forgiving, Merciful. 70 And should they but seek to play false with thee - well, they were false to God [Himself] ere this: but He gave [the believers] mastery over them. And God is all-knowing, wise. 71 Those who believe and migrated, and fought for the Cause of Allah with their wealth and their persons; and those who sheltered them and helped them shall be guides to each other. And those who believe, but have not emigrated you have no guidance towards them till they emigrate. But if they seek your help in the cause of your religion, it is your duty to help them, except against a nation with whom you have a treaty. Allah sees the things you do. 72 The unbelievers are each other's friends. If you (the believers) do not keep the same among yourselves in the land, there will come into being widespread idolatry and great evil. 73 And they who have attained to faith, and who have forsaken the domain of evil and are striving hard in God's cause, as well as those who shelter and succour [them] - it is they, they who are truly believers! Forgiveness of sins awaits them, and a most excellent sustenance. 74 And those who afterwards believed and left their homes and strove along with you, they are of you; and those who are akin are nearer one to another in the ordinance of Allah. Lo! Allah is Knower of all things. 75
