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 if they desire treachery against thee, they have tricked God before; but He has given thee power over them; and God is All-knowing, All-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 Those who accepted the faith and abandoned their homes, and struggled in the cause of God, and those who gave them shelter and helped them, are veritably true believers. For them is forgiveness and noble sustenance. 74 And those who afterwards believed and migrated and fought along with you – they too are from among you; and family members (blood relations) are nearer to one another in the Book of Allah; indeed Allah knows everything. 75
