(23) باب عَرَقِ الْجُنُبِ وَأَنَّ الْمُسْلِمَ لاَ يَنْجُسُ
Narrated Abu Huraira:
The Prophet (ﷺ) came across me in one of the streets of Medina and at that time I was Junub. So I slipped away from him and went to take a bath. On my return the Prophet (ﷺ) said, "O Abu Huraira! Where have you been?" I replied, "I was Junub, so I disliked to sit in your company." The Prophet (ﷺ) said, "Subhan Allah! A believer never becomes impure."
