وَعَنْ أَبِي سَعِيدٍ عَنِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ: (وهم فِيهَا كَالِحُونَ) قَالَ: «تَشْوِيهِ النَّارُ فَتَقَلَّصُ شَفَتُهُ الْعُلْيَا حَتَّى تَبْلُغَ وَسْطَ رَأْسِهِ وَتَسْتَرْخِي شَفَتُهُ السُّفْلَى حَتَّى تضرب سُرَّتَهُ» . رَوَاهُ التِّرْمِذِيّ

Abu Sa’id reported the Prophet as saying regarding “And they in it will be showing their teeth[*],” that the fire will roast a person and his upper lip will retract till it reaches the middle of his head, and his lower lip will hang down till it strikes his navel.” *Quran; 23:104 Tirmidhi transmitted it.
