﴿ إِنَّ ٱلْمُجْرِمِينَ فِى ضَلَٰلٍۢ وَسُعُرٍۢ ﴾

“for, behold, those who are lost in sin [will at that time come to know that it is they who] were sunk in error and folly!”

(Lo! the guilty) the idolaters: Abu Jahl and his host (are in error) in manifest error in the life of the world (and madness) toil and tiredness in hell.
