The Prophet ﷺ said regarding the verse "and they will be grimacing therein" [Muminun 23:104], "The Fire will disfigure them. Their upper lip will shrink back until it reaches the middle of their head, and their lower lip will droop down until it strikes their navel."
حدثنا سويد أخبرنا عبد الله بن المبارك عن سعيد بن يزيد أبي شجاع عن أبي السمح عن أبي الهيثم
عن النبي ﷺ قال {وهم فيها كالحون} قال تشويه النار فتقلص شفته العليا حتى تبلغ وسط رأسه وتسترخي شفته السفلى حتى تضرب سرته
