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 And if they desire treachery against thee, they have tricked God before; but He has given thee power over them; and God is All-knowing, 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 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 have believed afterwards and emigrated, and struggled with you -- they belong to you; but those related by blood are nearer to one another in the Book of God; surely God has knowledge of everything. 75
