O Prophet, say to whoever is in your hands of the captives, "If Allah knows [any] good in your hearts, He will give you [something] better than what was taken from you, and He will forgive you; and Allah is Forgiving and 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 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 The unbelievers, they are guides of one another. Unless you do this, there will be persecution in the land and great corruption. 73 And those who believed and migrated and fought in Allah's cause, and those who gave shelter and provided help – it is they who are the true believers; for them is pardon, and an honourable sustenance. 74 And those who have believed later on, and emigrated and struggled for God's sake alongside you are also a part of you. But as to blood relations, they are nearer one to another in the Book of God. God has full knowledge of all things. 75
