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).
