وَعَنْ أَبِي هُرَيْرَةَ
قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «تَحت كل شَعْرَة جَنَابَةٌ فَاغْسِلُوا الشَّعْرَ وَأَنْقُوا الْبَشْرَةَ»
The Prophet (sallallahu alayhi wa sallam) said:, “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 ibn Wajih who is the transmitter is a shaikh one cannot trust.”
