﴿ تَلْفَحُ وُجُوهَهُمُ ٱلنَّارُ وَهُمْ فِيهَا كَٰلِحُونَ ﴾

“the fire will scorch their faces, and they will abide therein with their lips distorted in pain.”

وَهُمْ فِيهَا كَالِحُونَ And they will be disfigured therein - 23:104). The word is used for a person whose lips do not meet and leave his teeth fully exposed, which looks very ugly. It is said that the upper lip of a person consigned to Hell will be drawn up and his lower lip will be drawn down so that his teeth will remain visible at all times.
