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 But if they seek to betray you, know that they had already betrayed Allah. Therefore He made you prevail over them. Allah is All-Knowing, All-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 And (as for) those who disbelieve, some of them are the guardians of others; if you will not do it, there will be in the land persecution and great mischief. 73 Those who believe, and adopt exile, and fight for the Faith, in the cause of Allah as well as those who give (them) asylum and aid,- these are (all) in very truth the Believers: for them is the forgiveness of sins and a provision most generous. 74 And those who believed afterwards and emigrated and strave hard along with you: these also are of you; and the kindred by blood are nearer unto one another in Allah's decree; verily Allah is of everything the Knower. 75
