He will say: Enter into fire among the nations that have passed away before you from among jinn and men; whenever a nation shall enter, it shall curse its sister, until when they have all come up with one another into it; the last of them shall say with regard to the foremost of them: Our Lord! these led us astray therefore give them a double chastisement of the fire. He will say: Every one shall have double but you do not know.

And mention the brother of Ad; when he warned his people in the sandy plains,-- and indeed warners came before him and after him-- saying Serve none but Allah; surely I fear for you the punishment of a grievous day.
