O Prophet, tell the captives you have taken: "If God finds some good in your hearts, He will reward you with something better than was taken away from you, and forgive your sins, for God is forgiving and kind." 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 Surely those who believed and fled (their homes) and struggled hard in Allah's way with their property and their souls, and those who gave shelter and helped-- these are guardians of each other; and (as for) those who believed and did not fly, not yours is their guardianship until they fly; and if they seek aid from you in the matter of religion, aid is incumbent on you except against a people between whom and you there is a treaty, and Allah sees 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 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
