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 If they try to deceive you, remember they have deceived God before. So He gave you mastery over them, for God is all-knowing and all-wise. 71 Lo! those who believed and left their homes and strove with their wealth and their lives for the cause of Allah, and those who took them in and helped them: these are protecting friends one of another. And those who believed but did not leave their homes, ye have no duty to protect them till they leave their homes; but if they seek help from you in the matter of religion then it is your duty to help (them) except against a folk between whom and you there is a treaty. Allah is Seer of what ye 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 believed and migrated and fought in Allah's cause, and those who gave shelter and provided help – it is they who are the true believers; for them is pardon, and an honourable sustenance. 74 And (as for) those who believed afterwards and fled and struggled hard along with you, they are of you; and the possessors of relationships are nearer to each other in the ordinance of Allah; surely Allah knows all things. 75
