Indeed, those who have believed and emigrated and fought with their wealth and lives in the cause of Allāh and those who gave shelter and aided - they are allies of one another. But those who believed and did not emigrate - for you there is no support of them until they emigrate. And if they seek help of you for the religion, then you must help, except against a people between yourselves and whom is a treaty. And Allāh is Seeing of what you do.
