God will say, "Enter the Fire and join the bands of jinn and men that have gone before you." Every time a host enters [the fire], it will curse its fellow-host, then, when they are all gathered there, the last of them will say of the first, "Our Lord, it was they who led us astray: give them double punishment in the Fire," -- God will say, "Every one of you will have double punishment, though you do not know it" --
