O Prophet! Say unto those 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 from you, and will forgive you. Lo! Allah is Forgiving, 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 Surely those who believed and migrated and strove hard in the way of Allah with their possessions and their lives, and those that sheltered and helped them - they alone are the true allies of one another. And those who believed but did not migrate (to Dar-al-Islam), you are under no obligation of alliance unless they migrate. And should they seek help from you in the matter of religion, it is incumbent on you to provide help unless it be against a people with whom you have a pact. Allah is cognizant of all that 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 believe and have migrated and strove in the way of Allah, and those who gave them refuge and help - it is they who are the true believers. Theirs shall be forgiveness and honourable sustenance. 74 And those who believed afterwards and emigrated and strave hard along with you: these also are of you; and the kindred by blood are nearer unto one another in Allah's decree; verily Allah is of everything the Knower. 75
