باب فِي شِدَّةِ حَرِّ نَارِ جَهَنَّمَ وَبُعْدِ قَعْرِهَا وَمَا تَأْخُذُ مِنَ الْمُعَذَّبِينَ
Sahih Muslim 2845 b

Samura b. Jundub reported Allah's Messenger (ﷺ) as saying:

There would be among them those to whom the fire will reach up to their ankels and to some of them the fire would reach their knees and to some it would reach their waists and to some it would reach up to their collar-bones.
حَدَّثَنِي عَمْرُو بْنُ زُرَارَةَ، أَخْبَرَنَا عَبْدُ الْوَهَّابِ، - يَعْنِي ابْنَ عَطَاءٍ - عَنْ سَعِيدٍ، عَنْ قَتَادَةَ، قَالَ سَمِعْتُ أَبَا نَضْرَةَ، يُحَدِّثُ عَنْ سَمُرَةَ بْنِ جُنْدَبٍ، أَنَّ النَّبِيَّ صلى الله عليه وسلم قَالَ ‏ "‏ مِنْهُمْ مَنْ تَأْخُذُهُ النَّارُ إِلَى كَعْبَيْهِ وَمِنْهُمْ مَنْ تَأْخُذُهُ النَّارُ إِلَى رُكْبَتَيْهِ وَمِنْهُمْ مَنْ تَأْخُذُهُ النَّارُ إِلَى حُجْزَتِهِ وَمِنْهُمْ مَنْ تَأْخُذُهُ النَّارُ إِلَى تَرْقُوَتِهِ ‏"‏ ‏.‏
