O Prophet! say unto the captives who are in your hands: if Allah knoweth any good in your hearts He will give you better than that which hath been taken away from you, and shall forgive you; and Allah is Forgiving, Merciful. 70 But if they have treacherous designs against thee, (O Messenger!), they have already been in treason against Allah, and so hath He given (thee) power over them. And Allah so He Who hath (full) knowledge and wisdom. 71 Those who believe and migrated, and fought for the Cause of Allah with their wealth and their persons; and those who sheltered them and helped them shall be guides to each other. And those who believe, but have not emigrated you have no guidance towards them till they emigrate. But if they seek your help in the cause of your religion, it is your duty to help them, except against a nation with whom you have a treaty. Allah 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 have believed afterwards and emigrated, and struggled with you -- they belong to you; but those related by blood are nearer to one another in the Book of God; surely God has knowledge of everything. 75
