the Prophet met him while he was Junub. He said: "[So I slipped away from him - meaning:] I withdrew - to perform Ghusl. Then he returned, so he said: 'Where have you been?' Or: 'Where did you go?' I replied: 'I was Junub.' So he said: 'Indeed the believer is not defiled.'''  

أَنَّ النَّبِيَّ ﷺ لَقِيَهُ وَهُوَ جُنُبٌ قَالَ فَانْبَجَسْتُ أَىْ فَانْخَنَسْتُ فَاغْتَسَلْتُ ثُمَّ جِئْتُ فَقَالَ أَيْنَ كُنْتَ أَوْ أَيْنَ ذَهَبْتَ قُلْتُ إِنِّي كُنْتُ جُنُبًا قَالَ إِنَّ الْمُسْلِمَ لاَ يَنْجُسُ قَالَ وَفِي الْبَابِ عَنْ حُذَيْفَةَ وَابْنِ عَبَّاسٍ
