Volume 1, Book 5, Number 281:
Narrated Abu Huraira:
The Prophet 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 said, “O Abu Huraira!
Where have you been?” I replied, “I was Junub, so I disliked to sit in your company.” The Prophet said,
“Subhan Allah! A believer never becomes impure.”
