Abdullah b. Mas`ud reported Allah's Messenger (ﷺ) as saying
Hell would be brought on that day (the Day of Judgment) with seventy thousand bridles, and seventy thousand angels dragging each bridle.
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.
This hadith has been narrated on the authority of Abn Huraira through another chain of transmitters with a slight variation of wording.
Abu Huraira reported
We were in the company of Allah's Messenger (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.
This hadith has been narrated on the authority of Abfi Huraira with the same chain of transmitters but with this change of wording that the Prophet (may. peace be upon him) said
It reached at its base and you heard its sound.
Samura b. Jundub reported Allah's Apostle (may peace -be upon him) as saying
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.
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.
This hadith has been narrated on the authority of Sa'id with the same chain of transmitters but with a slight variation of wording.
