Chapter 7, Verse 39

He will say, ‘Enter ye into the Fire among the nations of Jinn and men who passed away before you.’ Every time a people enters, it shall curse its sister (people) until, when they have all successively arrived therein, the last of them will say of the first of them: ‘Our Lord, these led us astray, so give them a double punishment of the Fire.’ He will say, ‘For each preceding party there shall be double punishment, but you do not know.’
