Sahih Muslim , Book 3, Hadith 65 (In-Book) ⓘ

Jabir b. 'Abdullah reported: When the Messenger of Allah took a bath because of sexual intercourse, he poured three handfuls of water upon his head. Hasan b. Muhammad said to him (the narrator): My hair is thick. Upon this Jabir observed. I said to him: O son of my brother, the hair of the Messenger of Allah was thicker than your hair and these were more fine (than yours).

وَحَدَّثَنَا مُحَمَّدُ بْنُ الْمُثَنَّى، حَدَّثَنَا عَبْدُ الْوَهَّابِ، - يَعْنِي الثَّقَفِيَّ - حَدَّثَنَا جَعْفَرٌ، عَنْ أَبِيهِ، عَنْ جَابِرِ بْنِ عَبْدِ اللَّهِ، قَالَ كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم إِذَا اغْتَسَلَ مِنْ جَنَابَةٍ صَبَّ عَلَى رَأْسِهِ ثَلاَثَ حَفَنَاتٍ مِنْ مَاءٍ ‏.‏ فَقَالَ لَهُ الْحَسَنُ بْنُ مُحَمَّدٍ إِنَّ شَعْرِي كَثِيرٌ ‏.‏ قَالَ جَابِرٌ فَقُلْتُ لَهُ يَا ابْنَ أَخِي كَانَ شَعْرُ رَسُولِ اللَّهِ صلى الله عليه وسلم أَكْثَرَ مِنْ شَعْرِكَ وَأَطْيَبَ ‏.‏
