Abu Hurairah was met by the Prophet in one of the streets of Al-Madinah when he was in a state of sexual impurity, so he slipped away. The Prophet missed him, so when he came (later on), he said: 'Where were you O Abu Hurairah?' He said: 'O Messenger of Allah, you met me when I was in a state of sexual impurity, and I did not want to sit with you until I had a bath. The Messenger of Allah said: 'The believer does not become impure.'"
