Bulugh al-Maram, Book 1, Hadith 134 (English) ⓘ
Narrated Abu Hurairah (RAA): Allah's Messenger (Peace be upon him) said: "There is Janabah (trace of sexual impurity) under every hair, so wash your hair and cleanse the skin." Abu Dawud and at-Tirmidhi transmitted it but they declared it to be weak.
وَعَنْ أَبِي هُرَيْرَةَ - رضى الله عنه - قَالَ: قَالَ رَسُولُ اَللَّهِ - صلى الله عليه وسلم -{ إِنَّ تَحْتَ كُلِّ شَعْرَةٍ جَنَابَةً, فَاغْسِلُوا اَلشَّعْرَ, وَأَنْقُوا اَلْبَشَرَ } رَوَاهُ أَبُو دَاوُدَ, وَاَلتِّرْمِذِيُّ وَضَعَّفَاه ُ (151). 5 - منكر. رواه أبو داود (248)، والترمذي (106).

Ahmad transmitted a similar narration to the above, on the authority of `A'ishah (RAA), but this version has an unknown transmitter.
وَلِأَحْمَدَ عَنْ عَائِشَةَ نَحْوُهُ, وَفِيهِ رَاوٍ مَجْهُول ٌ (152). 6 - ضعيف. رواه أحمد (654).
