Narrated AbuHurayrah:
The Messenger of Allah (ﷺ) said: There is sexual defilement under every hair; so wash the hair and cleanse the skin.
Abu Dawud said: The tradition narrated by Harith b. Wajih is rejected (Munkar).…
حَدَّثَنَا نَصْرُ بْنُ عَلِيٍّ الْجَهْضَمِيُّ، حَدَّثَنَا الْحَارِثُ بْنُ وَجِيهٍ، حَدَّثَنَا مَالِكُ بْنُ دِينَارٍ، عَنْ مُحَمَّدِ بْنِ سِيرِينَ، عَنْ أَبِي هُرَيْرَةَ، قَالَ قَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ " إِنَّ تَحْتَ كُلِّ شَعَرَةٍ جَنَابَةً فَاغْسِلُوا الشَّعَرَ وَأَنْقُوا الْبَشَرَةَ " .
It was narrated that Abu Hurairah said:
"The Messenger of Allah (ﷺ) said: 'Under every hair there is the state of sexual impurity, so wash the hair and cleanse the skin.'"
