Sahih al-Bukhari 283

Ali ibn Abdullah narrated to us, saying: Yahya narrated to us, saying: Humayd narrated to us, saying: Bakr narrated to us, from Abu Rafi, from Abu Hurayrah, that the Prophet (ﷺ) met him on one of the roads of Madinah while he was in a state of major ritual impurity. Abu Hurayrah slipped away from him, went and bathed, then returned. The Prophet (ﷺ) said: “Where were you, Abu Hurayrah?” He replied: “I was in a state of major ritual impurity, and I disliked sitting with you while I was not in a state of purity.” He said: “Glory be to Allah! A believer does not become impure.”
