Abu Huraira reported God's messenger as saying, "The distance between the shoulders of an infidel in hell will be a three days' journey for a swift rider." A version says the molar tooth of an infidel will be like Uhud and the thickness of his skin a three nights' journey. Muslim transmitted it.
وَعَنْ أَبِي هُرَيْرَةَ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «مَا بَيْنَ مَنْكِبَيِ الْكَافِرِ فِي النَّارِ مَسِيرَةَ ثَلَاثَةِ أَيَّامٍ لِلرَّاكِبِ الْمُسْرِعِ» . وَفِي رِوَايَةٍ: «ضِرْسُ الْكَافِرِ مِثْلُ أُحُدٍ وَغِلَظُ جِلْدِهِ مَسِيرَةُ ثَلَاثٍ» . رَوَاهُ مُسْلِمٌ
