He said, "Enter with the multitude of nations before you from humans and Jinn to the fire!" Every time a nation entered, it cursed its sister nation, until they are all gathered inside it; then the last of them says to the first: "Our Lord, these are the ones who have misguided us, so give them double the retribution of the fire!" He replied: "Each will receive double, but you do not know."
