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 But if they seek to betray you, they had betrayed Allah before, but He has let you overcome them. Allah is the Knower, the 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 striven hard in the way of Allah, those who sheltered and succoured - these! they are the believers in very truth; for them shall be forgiviness and honourable 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
