Sunan an-Nasai
أَخْبَرَنَا قُتَيْبَةُ، قَالَ حَدَّثَنَا أَبُو عَوَانَةَ، عَنْ دَاوُدَ الأَوْدِيِّ، عَنْ حُمَيْدِ بْنِ عَبْدِ الرَّحْمَنِ الْحِمْيَرِيِّ، قَالَ لَقِيتُ رَجُلاً صَحِبَ النَّبِيَّ صلى الله عليه وسلم كَمَا صَحِبَهُ أَبُو هُرَيْرَةَ أَرْبَعَ سِنِينَ قَالَ نَهَانَا رَسُولُ اللَّهِ صلى الله عليه وسلم أَنْ يَمْتَشِطَ أَحَدُنَا كُلَّ يَوْمٍ .
It was narrated that Humaid bin 'Abdur-Rahman Al-Himyari said: "I met a man who accompanied the Prophet [SAW] as Abu Hurairah accompanied him for four years, who said: 'The Messenger of Allah [SAW] forbade us from combing our hair everyday.'"
