Ash-Shama'il Al-Muhammadiyah, Book 3, Hadith 26 (In-Book)

Baraa bin Aazib R.A. reports: "Rasulullah was of average hight, and the portion between the two shoulders was wide. His hair was till his ear lobes".

حَدَّثَنَا أَحْمَدُ بْنُ مَنِيعٍ، قَالَ‏:‏ حَدَّثَنَا أَبُو قَطَنٍ، قَالَ‏:‏ حَدَّثَنَا شُعْبَةُ، عَنْ أَبِي إِسْحَاقَ، عَنِ الْبَرَاءِ بْنِ عَازِبٍ، قَالَ‏:‏ كَانَ رَسُولُ اللهِ صلى الله عليه وسلم مَرْبُوعًا، بَعِيدَ مَا بَيْنَ الْمِنْكَبَيْنِ، وَكَانَتْ جُمَّتُهُ تَضْرِبُ شَحْمَةَ أُذُنَيْهِ‏.‏
