Indeed those who have believed and migrated and waged jihād with their possessions and persons in the way of Allah, and those who gave [them] shelter and help —they are heirs of one another. As for those who have believed but did not migrate, you have no heirdom in relation to them whatsoever until they migrate. Yet if they ask your help for the sake of religion, it is incumbent on you to help them, excepting against a people with whom you have a treaty; and Allah sees best what you do.
