O Prophet! Say to the captives that are in your hands: "If Allah knows any good in your hearts, He will give you something better than what has been taken from you, and He will forgive you, and Allah is Oft-Forgiving, Most 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 (as for) those who believed and fled and struggled hard in Allah's way, and those who gave shelter and helped, these are the believers truly; they shall have forgiveness and honorable provision. 74 And as for those who henceforth come to believe, and who forsake the domain of evil and strive hard [in God's cause] together with you - these [too] shall belong to you; and they who are [thus] closely related have the highest claim on one another in [accordance with] God's decree. Verily, God has full knowledge of everything. 75
