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." 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 those who disbelieve are allies to one another, (and) if you (Muslims of the whole world collectively) do not do so (i.e. become allies, as one united block with one Khalifah - chief Muslim ruler for the whole Muslim world to make victorious Allah's Religion of Islamic Monotheism), there will be Fitnah (wars, battles, polytheism, etc.) and oppression on earth, and a great mischief and corruption (appearance of polytheism). 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
