عَنْ أَنَسٍ رَضِيَ اللَّهُ عَنْهُ قَالَ كَانَ شَعْرُ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ إِلَى أَنْصَافِ أُذُنَيْهِ وَفِي لَفْظٍ لَا يُجَاوِزُ أُذُنَيْهِ
Sayyiduna Anas (may Allah be pleased with him) narrates that the hair of the Noble Prophet (peace and blessings be upon him) would reach up to half of his ears. In another narration, it is stated: The hair of the Prophet (peace and blessings be upon him) would not go beyond his ears.
