حَدَّثَنَا نَصْرُ بْنُ عَلِيٍّ، حَدَّثَنِي الْحَارِثُ بْنُ وَجِيهٍ، حَدَّثَنَا مَالِكُ بْنُ دِينَارٍ، عَنْ مُحَمَّدِ بْنِ سِيرِينَ، عَنْ أَبِي هُرَيْرَةَ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏إِنَّ تَحْتَ كُلِّ شَعْرَةٍ جَنَابَةً فَاغْسِلُوا الشَّعْرَ وَأَنْقُوا الْبَشَرَ ‏"‏ ‏.‏ قَالَ أَبُو دَاوُدَ الْحَارِثُ بْنُ وَجِيهٍ حَدِيثُهُ مُنْكَرٌ وَهُوَ ضَعِيفٌ

Narrated AbuHurayrah

Nasr ibn Ali narrated to us, Al-Harith ibn Wajih narrated to me, Malik ibn Dinar narrated to us, from Muhammad ibn Sirin, from Abu Hurayrah, who said: The Messenger of Allah (ﷺ) said: "Indeed, under every hair is state of major ritual impurity (janabah), so wash the hair and cleanse the skin."

Abu Dawud said: The narration of Al-Harith ibn Wajih is rejected (munkar), and he is weak.
