Hell would be brought on that day (the Day of Judgment) with seventy thousand bridles, and seventy thousand angels dragging each bridle.  

قَالَ رَسُولُ اللَّهِ ﷺ يُؤْتَى بِجَهَنَّمَ يَوْمَئِذٍ لَهَا سَبْعُونَ أَلْفَ زِمَامٍ مَعَ كُلِّ زِمَامٍ سَبْعُونَ أَلْفَ مَلَكٍ يَجُرُّونَهَا  

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.  

أَنَّ النَّبِيَّ ﷺ 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  

This hadith has been narrated on the authority of Abn Huraira through another chain of transmitters with a slight variation of wording.  

عَنِ النَّبِيِّ ﷺ بِمِثْلِ حَدِيثِ أَبِي الزِّنَادِ غَيْرَ أَنَّهُ قَالَ كُلُّهُنَّ مِثْلُ حَرِّهَا  

We were in the company of Messenger of Allah ﷺ that we heard a terrible sound. Thereupon Allah's Apostle ﷺ said: Do you know what (sound) is this? We said: Allah and His Messenger know best. Thereupon he said: That is a stone which was thrown seventy years before in Hell and it has'been constantly slipping down and now it has reached its base.  

كُنَّا مَعَ رَسُولِ اللَّهِ ﷺ إِذْ سَمِعَ وَجْبَةً فَقَالَ النَّبِيُّ ﷺ تَدْرُونَ مَا هَذَا قَالَ قُلْنَا اللَّهُ وَرَسُولُهُ أَعْلَمُ قَالَ هَذَا حَجَرٌ رُمِيَ بِهِ فِي النَّارِ مُنْذُ سَبْعِينَ خَرِيفًا فَهُوَ يَهْوِي فِي النَّارِ الآنَ حَتَّى انْتَهَى إِلَى قَعْرِهَا  

It reached at its base and you heard its sound.  

وَقَالَ هَذَا وَقَعَ فِي أَسْفَلِهَا فَسَمِعْتُمْ وَجْبَتَهَا  

There will be some to whose ankels the fire will reach, some to whose knees, some to whose waist the fire will reach, and some to whose collar-bone the fire will reach.  

أَنَّهُ سَمِعَ نَبِيَّ اللَّهِ ﷺ يَقُولُ إِنَّ مِنْهُمْ مَنْ تَأْخُذُهُ النَّارُ إِلَى كَعْبَيْهِ وَمِنْهُمْ مَنْ تَأْخُذُهُ إِلَى حُجْزَتِهِ وَمِنْهُمْ مَنْ تَأْخُذُهُ إِلَى عُنُقِهِ  

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.  

أَنَّ النَّبِيَّ ﷺ 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  

This hadith has been narrated on the authority of Sa'id with the same chain of transmitters but with a slight variation of wording.  

حَدَّثَنَا سَعِيدٌ بِهَذَا الإِسْنَادِ وَجَعَلَ مَكَانَ حُجْزَتِهِ حَقْوَيْهِ
