O Prophet, say to those you have taken captive in your hand: 'If Allah finds goodness in your hearts, He will give you that which is better than what has been taken from you, and He will forgive you. Allah is Forgiving, the Most 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 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 The believers who left their homes, and strove for the cause of God and those who gave them refuge and helped them, are true believers. They will have forgiveness (from their Lord) and (will be granted) honorable provisions. 74 And those who afterwards believed and migrated and fought along with you – they too are from among you; and family members (blood relations) are nearer to one another in the Book of Allah; indeed Allah knows everything. 75
