Prophet, tell those you have taken captive: "If God knows of any good in your hearts, He will give you something better than what has been taken from you, and He will forgive you: God is Forgiving and 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 have believed and migrated and struggled for God's cause with their possessions and persons, and those who have given refuge and help, are the friends and protectors of one another. But as for those who have come to believe without having migrated -- you are in no way responsible for their protection until they migrate. If they seek your help in the matter of religion, it is incumbent on you to help them, except against a people with whom you have a pact. God sees what you do. 72 As for the unbelievers, they are friends one of another. Unless you do this, there will be persecution in the land and great corruption. 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 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
