Abu Hurairah narrated that the Messenger of Allah (s.a.w) said: "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.
