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.'"  

أَنَّهُ لَقِيَهُ النَّبِيُّ ﷺ فِي طَرِيقٍ مِنْ طُرُقِ الْمَدِينَةِ وَهُوَ جُنُبٌ فَانْسَلَّ فَفَقَدَهُ النَّبِيُّ ﷺ فَلَمَّا جَاءَ قَالَ أَيْنَ كُنْتَ يَا أَبَا هُرَيْرَةَ قَالَ يَا رَسُولَ اللَّهِ لَقِيتَنِي وَأَنَا جُنُبٌ فَكَرِهْتُ أَنْ أُجَالِسَكَ حَتَّى أَغْتَسِلَ فَقَالَ رَسُولُ اللَّهِ ﷺ الْمُؤْمِنُ لاَ يَنْجُسُ  

"The Prophet came out and met me when I was sexually impure, so I kept away from him. Then I had a bath and came to him. He said: 'What is the matter with you?' I said: 'I was sexually impure.' The Messenger of Allah said: 'The Muslim does not become impure.'"  

خَرَجَ النَّبِيُّ ﷺ فَلَقِيَنِي وَأَنَا جُنُبٌ فَحِدْتُ عَنْهُ فَاغْتَسَلْتُ ثُمَّ جِئْتُ فَقَالَ مَا لَكَ قُلْتُ كُنْتُ جُنُبًا قَالَ رَسُولُ اللَّهِ ﷺ إِنَّ الْمُسْلِمَ لاَ يَنْجُسُ
