It is narrated from Sayyiduna Anas bin Malik (may Allah be pleased with him); he said: I heard the Prophet (peace and blessings be upon him) saying: "This fire of yours (of the world) is one part of seventy parts of the fire of Hell. Had it not been quenched in water twice, you would not have been able to benefit from it. And by Allah! Even though this (former state) alone would have been sufficient, it still supplicates to Allah and seeks His refuge that He never return it into that (fire of Hell)." The chain of this hadith is sahih (authentic), but the two Shaykhs did not record it with this wording.

It is narrated from Sayyiduna Abdullah bin al-Harith bin Jaz' al-Zubaydi (may Allah be pleased with him), the Companion of the Prophet (peace and blessings be upon him), who relates from the Messenger of Allah (peace and blessings be upon him) that he (peace and blessings be upon him) said: "Indeed, in Hell there will be snakes like the necks of Bactrian (Khurasani) camels (thick and long). When one of these snakes bites someone (of the people of Hell) once, he will feel its burning and pain for forty years." The chain of this hadith is sahih (authentic), but the two Shaykhs did not record it.

It is narrated from Masruq that Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) said concerning this saying of Allah Almighty: "We will increase them in punishment upon punishment." [Surah al-Nahl: 88] : "(This punishment refers to) scorpions whose stings will be like tall date-palms." This hadith is sahih (authentic) on the condition of the two Shaykhs (Bukhari and Muslim), but they did not record it.

It is narrated from Sayyiduna Abdullah bin Amr (may Allah be pleased with them both); he said that the Messenger of Allah (peace and blessings be upon him) said: "Indeed, between each of the earths and the next earth there is a distance of five hundred years. The uppermost of them rests on the back of a fish whose two ends meet in the sky, the fish rests on the back of a rock, and the rock is in the hand of an angel. The second earth is the prison of the wind. When Allah Almighty intended to destroy the people of Ad, He commanded the keeper (angel) of the wind to send upon them a wind that would destroy Ad. He (the angel) said: 'O my Lord! Shall I release upon them wind the size of a bull's nostril?' Allah, the Compeller, the Mighty and Majestic, said to him: 'Then it would overturn the earth and everything on it. Rather, release upon them wind the size of the hole of a ring.' This is the wind about which Allah Almighty said in His Mighty Book: 'It left nothing it came upon but that it made it like decayed bones.' [Surah al-Dhariyat: 42] The third earth contains the stones of Hell, and the fourth earth contains the sulphur of Hell." The Companions (may Allah be pleased with them) said: O Messenger of Allah! Is there sulphur in Hell too? He (peace and blessings be upon him) said: "Yes, by the One in whose Hand is my soul! Indeed, in it there are valleys of sulphur such that if even firm mountains were cast into them, they would melt. The fifth earth contains the snakes of Hell; their mouths are as wide as valleys, and they will bite the disbeliever such that no flesh will remain on his bones. The sixth earth contains the scorpions of Hell; the smallest scorpion among them is the size of saddled mules, and it will sting the disbeliever such that its pain will make him forget the heat of Hell. The seventh earth is Saqar, and in it Iblis is bound in chains of iron, one hand in front of him and one hand tied behind him. Then, when Allah intends to release him upon whomever He wills of His servants, He releases him." Abu al-Samh is alone in narrating this hadith from Isa bin Hilal, and I have previously mentioned his reliability ('adalah) with the explicit statement of Imam Yahya bin Ma'in (may Allah have mercy on him). This hadith is sahih (authentic), but the two Shaykhs did not record it.

It is narrated from Sayyidah Aishah (may Allah be pleased with her); she said: "When this verse of Surah al-Muzzammil was revealed: 'And leave Me with the deniers, the people of ease and luxury, and give them respite for a little while. Indeed, with Us are heavy shackles and a blazing Fire.' [Surah al-Muzzammil: 11-12] , only a short time later the Battle of Badr took place." This hadith is sahih (authentic) on the condition of Imam Muslim, but the two Shaykhs did not record it.

It is narrated from Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him); he said that the Messenger of Allah (peace and blessings be upon him) said: "On that Day Hell will be brought, and it will have seventy thousand reins, and with each rein there will be seventy thousand angels pulling it." This hadith is sahih (authentic) on the condition of Imam Muslim, but the two Shaykhs did not record it.

It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him); he said that the Messenger of Allah (peace and blessings be upon him) said: "On the Day of Resurrection the molar tooth of the disbeliever will be the size of (Mount) Uhud, the thickness of his skin will be seventy cubits, his upper arm will be the size of (Mount) Bayda', his thigh will be the size of (Mount) Wariqan, and his seat in Hell will be as large as the distance between me (in Madinah) and al-Rabadhah." The chain of this hadith is sahih (authentic), but the two Shaykhs did not record it with this wording; rather, they both agreed only on the mention of the disbeliever's molar tooth.

It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "The thickness of the disbeliever's skin will be forty-two cubits by the cubit of the Jabbar (a giant man), and his molar tooth will be like (Mount) Uhud." This hadith is sahih (authentic) on the condition of the two Shaykhs (Bukhari and Muslim), but they did not record it. Shaykh Abu Bakr (may Allah have mercy on him) said: The meaning of his (peace and blessings be upon him) words "by the cubit of the Jabbar" is: a giant from among the giants of mankind who lived in the earliest generations, whose build was very large and whose limbs and forearms were longer than those of us humans.

It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that he said: "On the Day of Resurrection the molar tooth of the disbeliever will be like (Mount) Uhud, his head will be like (Mount) Bayda', his thigh will be like (Mount) Wariqan, the thickness of his skin will be seventy cubits, and his seat in Hell will be equal to the distance between Madinah and al-Rabadhah." Sayyiduna Abu Hurayrah (may Allah be pleased with him) said: And it used to be said: "His belly will be the size of (the valley of) Idam." The chain of this hadith is sahih (authentic) on the condition of the two Shaykhs (Bukhari and Muslim), but they did not record it because it stops at Sayyiduna Abu Hurayrah (may Allah be pleased with him) (mawquf).

It is narrated from Ya'la (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "This sea is itself Hell." The people said to Ya'la: Allah Almighty has said: "A Fire whose enclosing walls will surround them." [Surah al-Kahf: 29] He said: "By the One in whose Hand is my soul! I will never enter it until I meet Allah, and not a single drop of it will reach me." The chain of this hadith is sahih (authentic). Its meaning is that the sea is so perilous that it is as if it were Hell. That is why the recording of this hadith of Sayyiduna Abdullah bin Amr (may Allah be pleased with them both) from the Prophet (peace and blessings be upon him) branches off from it: "Beneath the sea there is fire, and beneath the fire there is sea; as for the Fire, it is beneath the seventh (earth)." And the Companions and those after them have testified to seeing its smoke!
