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 And should they but seek to play false with thee - well, they were false to God [Himself] ere this: but He gave [the believers] mastery over them. And God is all-knowing, wise. 71 Those who have believed and migrated and struggled for God's cause with their possessions and persons, and those who have given refuge and help, are the friends and protectors of one another. But as for those who have come to believe without having migrated -- you are in no way responsible for their protection until they migrate. If they seek your help in the matter of religion, it is incumbent on you to help them, except against a people with whom you have a pact. God 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 Those who have believed and migrated and striven for the cause of God, as well as those who have given them refuge and support, are the true believers; they shall have forgiveness and an honourable provision. 74 And as for those who henceforth come to believe, and who forsake the domain of evil and strive hard [in God's cause] together with you - these [too] shall belong to you; and they who are [thus] closely related have the highest claim on one another in [accordance with] God's decree. Verily, God has full knowledge of everything. 75
