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.
