عَنْ أَبِي رِمْثَةَ رَضِيَ اللَّهُ عَنْهُ قَالَ كَانَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ يَخْضِبُ بِالْحِنَّاءِ وَالْكَتَمِ وَكَانَ شَعْرُهُ يَبْلُغُ كَتِفَيْهِ أَوْ مَنْكِبَيْهِ
Sayyiduna Abu Rimthah (may Allah be pleased with him) narrates that the Noble Prophet (peace and blessings be upon him and his family) used to dye his hair with henna and katam, and his hair would reach his shoulders.
