O Prophet! say to those of the captives who are in your hands: If Allah knows anything good in your hearts, He will give to you better than that which has been taken away from you and will forgive you, and Allah is Forgiving, Merciful. 70 And if they desire treachery against thee, they have tricked God before; but He has given thee power over them; and God is All-knowing, All-wise. 71 Surely those who believed and migrated and strove hard in the way of Allah with their possessions and their lives, and those that sheltered and helped them - they alone are the true allies of one another. And those who believed but did not migrate (to Dar-al-Islam), you are under no obligation of alliance unless they migrate. And should they seek help from you in the matter of religion, it is incumbent on you to provide help unless it be against a people with whom you have a pact. Allah is cognizant of all that 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 And they who have attained to faith, and who have forsaken the domain of evil and are striving hard in God's cause, as well as those who shelter and succour [them] - it is they, they who are truly believers! Forgiveness of sins awaits them, and a most excellent 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
