Narrated Abu Huraira:
حَدَّثَنَا عَيَّاشٌ ، قَالَ حَدَّثَنَا عَبْدُ الأَعْلَى ، حَدَّثَنَا حُمَيْدٌ ، عَنْ بَكْرٍ ، عَنْ أَبِي رَافِعٍ ، عَنْ أَبِي هُرَيْرَةَ ، قَالَ لَقِيَنِي رَسُولُ اللَّهِ صلى الله عليه وسلم وَأَنَا جُنُبٌ، فَأَخَذَ بِيَدِي، فَمَشَيْتُ مَعَهُ حَتَّى قَعَدَ فَانْسَلَلْتُ، فَأَتَيْتُ الرَّحْلَ، فَاغْتَسَلْتُ ثُمَّ جِئْتُ وَهْوَ قَاعِدٌ فَقَالَ " أَيْنَ كُنْتَ يَا أَبَا هِرٍّ " فَقُلْتُ لَهُ. فَقَالَ " سُبْحَانَ اللَّهِ يَا أَبَا هِرٍّ إِنَّ الْمُؤْمِنَ لاَ يَنْجُسُ " .
Allah's Messenger (ﷺ) came across me and I was Junub. He took my hand and I went along with him till he sat down I slipped away, went home and took a bath. When I came back, he was still sitting there. He then said to me, "O Abu Huraira! Where have you been?' I told him about it. The Prophet (ﷺ) said, "Subhan Allah! O Abu Huraira! A believer never becomes impure."
