7.38 . He saith : Enter into the Fire among nations of the jinn and humankind who passed away before you . Every time a nation entereth , it curseth its sister ( nation ) till , when they have all been made to follow one another thither , the last of them saith unto the first of them : Our Lord! These led us astray , so give them double torment of the Fire . He saith : For each one there is double ( torment ) , but ye know not .
