He will say, “Join the crowds of jinn and humans who have gone into the Fire before you.” Every time a crowd enters, it will curse its sister-crowd. Until, when they are all in it, the last of them will say to the first of them, “Our Lord, these are the ones who misled us, so inflict on them a double punishment in the Fire.” He will say, “Each will have a double, but you do not know.”
