O Prophet! say to those who are captives in your hands: "If Allah findeth any good in your hearts, He will give you something better than what has been taken from you, and He will forgive you: for Allah is Oft-forgiving, Most Merciful." 70 And if they would betray thee, they betrayed Allah before, and He gave (thee) power over them. Allah is Knower, 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 The unbelievers are each other's friends. If you (the believers) do not keep the same among yourselves in the land, there will come into being widespread idolatry and great evil. 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
