Messenger of Allah 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."  

لَقِيَنِي رَسُولُ اللَّهِ ﷺ 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
