(13) باب النَّارُ يَدْخُلُهَا الْجَبَّارُونَ وَالْجَنَّةُ يَدْخُلُهَا الضُّعَفَاءُ
It is transmitted on the authority of Abu Huraira that Allah's Messenger (ﷺ) said:
The molar tooth of an unbeliever or the canine teeth of an unbeliever will be like Uhud and the thickness of his skin a three night's journey.
