O Prophet! Say to the captives that are in your hands: "If Allah knows any good in your hearts, He will give you something better than what has been taken from you, and He will forgive you, and Allah is Oft-Forgiving, Most Merciful." 70 And if they would betray thee, they betrayed Allah before, and He gave (thee) power over them. Allah is Knower, 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 Those who accepted the faith and left their homes and fought by your side, are your brothers; yet those who are related by blood are closer to one another according to the decree of God. Verily God knows everything. 75
