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 if they intend to act unfaithfully towards you, so indeed they acted unfaithfully towards Allah before, but He gave (you) mastery over them; and Allah is 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 those who believe, and have emigrated and struggled in the way of God. those who have given refuge and help those in truth are the believers, and theirs shall be forgiveness and generous provision. 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
