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, they had betrayed Allah before, but He has let you overcome them. Allah is the Knower, the Wise. 71 Those who believe and migrated, and fought for the Cause of Allah with their wealth and their persons; and those who sheltered them and helped them shall be guides to each other. And those who believe, but have not emigrated you have no guidance towards them till they emigrate. But if they seek your help in the cause of your religion, it is your duty to help them, except against a nation with whom you have a treaty. Allah sees the things you do. 72 Those who are infidels aid one another. Unless you do the same there will be discord in the land and anarchy. 73 But those who have believed and emigrated and fought in the cause of Allah and those who gave shelter and aided - it is they who are the believers, truly. For them is forgiveness and noble provision. 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
