وَعَنْ أَبِي هُرَيْرَةَ قَالَ: قَالَ رَسُولُ اللَّهِ صلى الله عَلَيْهِ وَسلم: «تَحت كل شَعْرَة جَنَابَةٌ فَاغْسِلُوا الشَّعْرَ وَأَنْقُوا الْبَشْرَةَ» . رَوَاهُ أَبُو دَاوُدَ وَالتِّرْمِذِيُّ وَابْنُ مَاجَهْ وَقَالَ التِّرْمِذِيُّ: هَذَا حَدِيثٌ غَرِيبٌ وَالْحَارِثُ بْنُ وَجِيهٍ الرَّاوِي وَهُوَ شيخ لَيْسَ بذلك
Abu Huraira reported God's messenger as saying, “There is sexual defilement under every hair, so wash the hair and cleanse the skin.” Abu Dawud, Tirmidhi and Ibn Majah transmitted it, and Tirmidhi said, “This is a gharib tradition, and al-Harith b. Wajih who is the transmitter is a shaikh one cannot trust.”
