Sahih Muslim · Hadith 6210
The Book Pertaining to the Excellent Qualities of the Holy Prophet (may Peace be upon them) and His - كتاب الفضائل
حدثنا محمد بن المثنى، ومحمد بن بشار، قالا حدثنا محمد بن جعفر، حدثنا شعبة، قال سمعت أبا إسحاق، قال سمعت البراء، يقول كان رسول الله صلى الله عليه وسلم رجلا مربوعا بعيد ما بين المنكبين عظيم الجمة إلى شحمة أذنيه عليه حلة حمراء ما رأيت شيئا قط أحسن منه صلى الله عليه وسلم .
Al-Bara' reported that Allah's Messenger (may peace be upon him) was of medium height, having broad shoulders, with his hair hanging down on the lobes of his ears. He put on a red mantle over him, and never have I seen anyone more handsome than Allah's Apostle (may peace be upon him).
