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 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 The believers who left their homes and strove for the cause of God, through their property and in person and those who gave refuge to them and helped them will be each other's guardians. The believers who did not leave their homes are not your guardians until they too leave their homes. If they ask you for help in a religious cause, you must help them against their enemies unless their enemies have a peace treaty with you. God is Well Aware of what you 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 they who have attained to faith, and who have forsaken the domain of evil and are striving hard in God's cause, as well as those who shelter and succour [them] - it is they, they who are truly believers! Forgiveness of sins awaits them, and a most excellent sustenance. 74 Those who accepted the faith later, left their homes and strove with you for the cause of God are also your people. They relatives are nearer to each other according to the Book of God. God has knowledge of all things. 75
