Hadith: I have never seen anyone with shoulder-length hair and wearing a red garment more beautiful than the Messenger of Allah (may Allah's peace and blessings be upon him).

عن البراء بن عازب رضي الله عنهما قال: «ما رأيتُ من ذِي لِمَّةٍ في حُلَّةٍ حَمْرَاءَ أحسنَ من رسول الله صلى الله عليه وسلم ، له شَعْرٌ يَضْرِبُ مَنْكِبَيْهِ، بعيدُ ما بين المَنْكِبَيْنِ، ليس بالقصير ولا بالطويل».
[صحيح] - [متفق عليه]

Al-Barā’ ibn ‘Āzib (may Allah be pleased with him) reported: I have never seen anyone with shoulder-length hair and wearing a red garment more beautiful than the Messenger of Allah (may Allah's peace and blessings be upon him). He had shoulder-length hair and broad shoulders and was neither short nor tall.
[Authentic hadith] - [Narrated by Bukhari & Muslim]

Explanation

In this Hadīth, Al-Barā’ ibn ‘Āzib (may Allah be pleased with him) describes the Prophet (may Allah's peace and blessings be upon him) in a way that indicates his beauty and handsomeness. He says that he never saw anyone whose hair reaches his earlobes and wearing a red garment more good-looking than the Messenger of Allah (may Allah's peace and blessings be upon him). Then, he mentions something else from his description: that he was broad-shouldered and that he was neither too tall nor too short.
