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 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 But those who have believed and emigrated and fought in the cause of Allah and those who gave shelter and aided - it is they who are the believers, truly. For them is forgiveness and noble provision. 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
