O Prophet, tell the captives you have taken: "If God finds some good in your hearts, He will reward you with something better than was taken away from you, and forgive your sins, for God is forgiving and kind." 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 have emigrated and struggled with their possessions and their selves in the way of God, and those who have given refuge and help -- those are friends one of another. And those who believe, but have not emigrated -- you have no duty of friendship towards them till they emigrate; yet if they ask you for help, for religion's sake, it is your duty to help them, except against a people between whom and you there is a compact; and God 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 have believed afterwards and emigrated, and struggled with you -- they belong to you; but those related by blood are nearer to one another in the Book of God; surely God has knowledge of everything. 75
