I said, ""No, I shall not disbelieve in Muhammad till you die and then be resurrected."" He said, ""Will I die and then be resurrected?"" I said, 'Yes'. He said', ""Then I will have wealth and children there, and I will pay you (there)."" So this Verse was revealed:-- 'Have you then seen him who disbelieved in Our Signs and (yet) says: I shall certainly be given wealth and children?
