[Machine] The Prophet ﷺ said, "Under every hair is impurity, so wash the hair and clean the skin underneath it." It was narrated by Harith bin Waji'i and Harith bin Waji'i spoke about it.
أَنَّ النَّبِيَّ ﷺ قَالَ تَحْتَ كُلِّ شَعْرٍ جَنَابَةٌ فَاغْسِلُوا الشَّعْرَ وَأَنْقُوا الْبَشَرَةَ تَفَرَّدَ بِهِ مَوْصُولًا الْحَارِثُ بْنُ وَجِيهٍ وَالْحَارِثُ بْنُ وَجِيهٍ تَكَلَّمُوا فِيهِ
