Abu Hudhaifah reported :

The Messenger of Allah ﷺ met me on one of the streets of medina while I was sexually defiled. I retreated and went away. I then took a bath and came to him. He asked : Where were you, O Abu Hurairah? I replied : As I was sexually defiled, I disliked to sit in your company without purification. He exclaimed: Glory be to Allah! A Muslim is not defiled.

He (Abu Dawud) said : The version of this tradition reported by Bishr has the chain: Humaid reported from Bakr.

حَدَّثَنَا مُسَدَّدٌ، حَدَّثَنَا يَحْيَى، وَبِشْرٌ، عَنْ حُمَيْدٍ، عَنْ بَكْرٍ، عَنْ أَبِي رَافِعٍ، عَنْ أَبِي هُرَيْرَةَ، قَالَ لَقِيَنِي رَسُولُ اللَّهِ ﷺ فِي طَرِيقٍ مِنْ طُرُقِ الْمَدِينَةِ وَأَنَا جُنُبٌ فَاخْتَنَسْتُ فَذَهَبْتُ فَاغْتَسَلْتُ ثُمَّ جِئْتُ فَقَالَ " أَيْنَ كُنْتَ يَا أَبَا هُرَيْرَةَ " . قَالَ قُلْتُ إِنِّي كُنْتُ جُنُبًا فَكَرِهْتُ أَنْ أُجَالِسَكَ عَلَى غَيْرِ طَهَارَةٍ . فَقَالَ " سُبْحَانَ اللَّهِ إِنَّ الْمُسْلِمَ لاَ يَنْجُسُ " . وَقَالَ فِي حَدِيثِ بِشْرٍ حَدَّثَنَا حُمَيْدٌ حَدَّثَنِي بَكْرٌ .
