O Prophet! say unto the 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 away from you, and shall forgive you; and Allah is Forgiving, Merciful. 70 But if they seek to betray you, know that they had already betrayed Allah. Therefore He made you prevail over them. Allah 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 The Unbelievers are protectors, one of another: Unless ye do this, (protect each other), there would be tumult and oppression on earth, and great mischief. 73 The believers who left their homes, and strove for the cause of God and those who gave them refuge and helped them, are true believers. They will have forgiveness (from their Lord) and (will be granted) honorable provisions. 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
