Ibn `Umar reported the Prophet as saying, "The inhabitants of hell will become huge in hell so that the space between the lobe of the ear and the shoulder of one of them will be a journey of seven hundred years, the thickness of his skin will be seventy cubits, and his molar tooth will be like Uhud."
عَنِ ابْنِ عُمَرَ عَنِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ: «يَعْظُمُ أَهْلُ النَّارِ فِي النَّارِ حَتَّى إِنَّ بَيْنَ شَحْمَةِ أُذُنِ أَحَدِهِمْ إِلَى عَاتِقِهِ مَسِيرَةَ سبعمائةِ عامٍ وإِنَّ غِلَظَ جلدِه سَبْعُونَ ذراعان وَإِن ضرسه مثل أحد»
