"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, (and he had) broad shoulders (and he was) not too short and not too long." (Using translation from Tirmidhī 1724)
مَا رَأَيْتُ مِنْ ذِي لِمَّةٍ أَحْسَنَ فِي حُلَّةٍ حَمْرَاءَ مِنْ رَسُولِ اللهِ ﷺ لَهُ شَعْرٌ يَضْرِبُ مَنْكِبَيْهِ بَعِيدُ مَا بَيْنَ الْمَنْكِبَيْنِ لَيْسَ بِالطَّوِيلِ وَلَا بِالْقَصِيرِ
