Narrated Al-Bara:
حَدَّثَنَا مَحْمُودُ بْنُ غَيْلاَنَ ، حَدَّثَنَا وَكِيعٌ ، حَدَّثَنَا سُفْيَانُ ، عَنْ أَبِي إِسْحَاقَ ، عَنِ الْبَرَاءِ ، قَالَ مَا رَأَيْتُ مِنْ ذِي لِمَّةٍ فِي حُلَّةٍ حَمْرَاءَ أَحْسَنَ مِنْ رَسُولِ اللَّهِ صلى الله عليه وسلم لَهُ شَعْرٌ يَضْرِبُ مَنْكِبَيْهِ بَعِيدٌ مَا بَيْنَ الْمَنْكِبَيْنِ لَمْ يَكُنْ بِالْقَصِيرِ وَلاَ بِالطَّوِيلِ . قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ .
"I have not seen anyone with hair past his shoulders in a red Hullah more handsome than the Messenger of Allah (ﷺ). He had hair that would flow on his shoulders, having broad shoulders, not too short and not too tall."
