باب فِي شِدَّةِ حَرِّ نَارِ جَهَنَّمَ وَبُعْدِ قَعْرِهَا وَمَا تَأْخُذُ مِنَ الْمُعَذَّبِينَ
Sahih Muslim 2843 a

Abu Huraira reported Allah's Apostle (ﷺ) as saying:

The fire which sons of Adam burn is only one-seventieth part of the Fire of Hell. His Companions said: By Allah, even ordinary fire would have been enough (to burn people). Thereupon he said: It is sixty-nine parts in excess of (the heat of) fire in this world each of them being equivalent to their heat.
حَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، حَدَّثَنَا الْمُغِيرَةُ، - يَعْنِي ابْنَ عَبْدِ الرَّحْمَنِ الْحِزَامِيَّ - عَنْ أَبِي الزِّنَادِ، عَنِ الأَعْرَجِ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ النَّبِيَّ صلى الله عليه وسلم قَالَ ‏"‏ نَارُكُمْ هَذِهِ الَّتِي يُوقِدُ ابْنُ آدَمَ جُزْءٌ مِنْ سَبْعِينَ جُزْءًا مِنْ حَرِّ جَهَنَّمَ ‏"‏ ‏.‏ قَالُوا وَاللَّهِ إِنْ كَانَتْ لَكَافِيَةً يَا رَسُولَ اللَّهِ ‏.‏ قَالَ ‏"‏ فَإِنَّهَا فُضِّلَتْ عَلَيْهَا بِتِسْعَةٍ وَسِتِّينَ جُزْءًا كُلُّهَا مِثْلُ حَرِّهَا ‏"‏ ‏.‏
