'Where were you, O Abu Hurairah?' He said: 'O Messenger of Allah, you met us but I was Junub, and I did not want to sit in your presence until I had performed Ghusl.' He said: 'Subhan Allah! The believer is not made impure (Najis).'"
أَنَّ النَّبِيَّ ﷺ لَقِيَهُ فِي طَرِيقٍ مِنْ طُرُقِ الْمَدِينَةِ وَهُوَ جُنُبٌ فَانْسَلَّ عَنْهُ فَاغْتَسَلَ فَفَقَدَهُ النَّبِيُّ ﷺ فَلَمَّا جَاءَ قَالَ أَيْنَ كُنْتَ يَا أَبَا هُرَيْرَةَ قَالَ يَا رَسُولَ اللَّهِ إِنَّكَ لَقِيتَنِي وَأَنَا جُنُبٌ فَكَرِهْتُ أَنْ أُجَالِسَكَ حَتَّى أَغْتَسِلَ فَقَالَ سُبْحَانَ اللَّهِ إِنَّ الْمُؤْمِنَ لاَ يَنْجُسُ
