Shaking hands with one who is in a state of sexual impurity
حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا إِسْمَاعِيلُ ابْنُ عُلَيَّةَ، عَنْ حُمَيْدٍ، عَنْ بَكْرِ بْنِ عَبْدِ اللَّهِ، عَنْ أَبِي رَافِعٍ، عَنْ أَبِي هُرَيْرَةَ، أَنَّهُ لَقِيَهُ النَّبِيُّ ـ صلى الله عليه وسلم ـ فِي طَرِيقٍ مِنْ طُرُقِ الْمَدِينَةِ وَهُوَ جُنُبٌ فَانْسَلَّ فَفَقَدَهُ النَّبِيُّ ـ صلى الله عليه وسلم ـ فَلَمَّا جَاءَ قَالَ " أَيْنَ كُنْتَ يَا أَبَا هُرَيْرَةَ " . قَالَ يَا رَسُولَ اللَّهِ لَقِيتَنِي وَأَنَا جُنُبٌ فَكَرِهْتُ أَنْ أُجَالِسَكَ حَتَّى أَغْتَسِلَ . فَقَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ " الْمُؤْمِنُ لاَ يَنْجُسُ " .
It was narrated from Abu Rafi' that : Abu Hurairah was met by the Prophet (ﷺ) in one of the streets of Al-Madinah when he was in a state of sexual impurity, so he slipped away. The Prophet (ﷺ) 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 (ﷺ) said: 'The believer does not become impure.'"
