مسند أحمد

It was narrated from `Ali bin Abi Talib (رضي الله عنه) that He described the Prophet (ﷺ) and said: He had a large head, a reddish white complexion, a large beard, large joints and large hands and feet. He had a long line of hair running from his chest to his navel and the hair on his head was thick and slightly wavy. He used to lean forward when walking as if he was walking uphill, and he was neither tall nor short, I have never seen anyone like him (ﷺ) before or since. ‘Ali bin Hakeem said in his hadeeth: ‘Ali bin Abi Talib (رضي الله عنه) described the Messenger of Allah (ﷺ) to us. He said: He had a large head and beautiful, slightly wavy hair.
