"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."  

عَنِ النَّبِيِّ ﷺ قَالَ إِنَّ غِلَظَ جِلْدِ الْكَافِرِ اثْنَانِ وَأَرْبَعُونَ ذِرَاعًا وَإِنَّ ضِرْسَهُ مِثْلُ أُحُدٍ وَإِنَّ مَجْلِسَهُ مِنْ جَهَنَّمَ كَمَا بَيْنَ مَكَّةَ وَالْمَدِينَةِ هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ غَرِيبٌ مِنْ حَدِيثِ الأَعْمَشِ  

"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.  

قَالَ رَسُولُ اللَّهِ ﷺ ضِرْسُ الْكَافِرِ يَوْمَ الْقِيَامَةِ مِثْلُ أُحُدٍ وَفَخِذُهُ مِثْلُ الْبَيْضَاءِ وَمَقْعَدُهُ مِنَ النَّارِ مَسِيرَةَ ثَلاَثٍ مِثْلُ الرَّبَذَةِ  

"The molar teeth of the disbeliever will be like Uhud (mountain)."  

ضِرْسُ الْكَافِرِ مِثْلُ أُحُدٍ  

'Indeed the disbeliever's tongue will be stretched a Farsakh or two Farsakh, such that the people will walk upon it."  

قَالَ رَسُولُ اللَّهِ ﷺ إِنَّ الْكَافِرَ لَيُسْحَبُ لِسَانُهُ الْفَرْسَخَ وَالْفَرْسَخَيْنِ يَتَوَطَّؤُهُ النَّاسُ
