Al-Adab Al-Mufrad, Book 56, Hadith 1315 (English) ⓘ

Muhammad ibn al-Hanafiyya said, "The Prophet, may Allah bless him and grant him peace, had a large head and large eyes. When he walked, he bent forward as if he was walking up a hill. When he turned around, he turned completely."

حَدَّثَنَا مُوسَى بْنُ إِسْمَاعِيلَ، قَالَ‏:‏ حَدَّثَنَا حَمَّادٌ، عَنِ ابْنِ عَقِيلٍ، عَنْ مُحَمَّدِ بْنِ عَلِيٍّ ابْنِ الْحَنَفِيَّةِ، عَنْ أَبِيهِ قَالَ‏:‏ كَانَ النَّبِيُّ صلى الله عليه وسلم ضَخْمَ الرَّأْسِ، عَظِيمَ الْعَيْنَيْنِ، إِذَا مَشَى تَكَفَّأَ، كَأَنَّمَا يَمْشِي فِي صَعَدٍ، إِذَا الْتَفَتَ الْتَفَتَ جَمِيعًا‏.‏
