"Indeed a disbeliever's skin will be forty-two forearm lengths thick, his molar teeth will be like Uhud (mountain), and his sitting place in Hell will be like what is between Makkah and Al-Madinah."
Jami` at-Tirmidhi Book 39, Hadith 5
← Previous Hadith "As-Saud is a mountain in the Fire, a disbeliever will be raised upon it for seventy autumns and then similarly he will fall down it, forever." (Daif)

Jami` at-Tirmidhi Book 39, Hadith 4 Next Hadith → "The molar teeth of the disbeliever on the Day of Judgment will be like Uhud (mountain), his thigh will be like Al-Baida, and his seat in the Fire will be like the distance of three the likes of Ar-Rabadhah." His SAW statement: "The likes of Ar-Rabadhah" means: like what is between Al-Madinah and ArRabadhah. And Al-Baidã' is a mountain like Uhud.
