Hadith 5060
أَخْبَرَنَا مُحَمَّدُ بْنُ عَبْدِ اللَّهِ بْنِ عَمَّارٍ، قَالَ حَدَّثَنَا الْمُعَافَى، عَنْ إِسْرَائِيلَ، عَنْ أَبِي إِسْحَاقَ، عَنِ الْبَرَاءِ، قَالَ مَا رَأَيْتُ أَحَدًا أَحْسَنَ فِي حُلَّةٍ حَمْرَاءَ مِنْ رَسُولِ اللَّهِ صلى الله عليه وسلم وَجُمَّتُهُ تَضْرِبُ مَنْكِبَيْهِ .
It was narrated that Al-Bara' said:
"I have never seen anyone who looked more handsome in a red Hullah than the Messenger of Allah [SAW], with his long hair that came down to his shoulders."
