مسند أحمد

It was narrated from Muhammad bin `Ali (رضي الله عنه), that his father said: The Messenger of Allah (ﷺ) had a large head, big eyes with long eyelashes, reddish eyes, a thick beard, a pinkish colour and large hands and feet; when he walked, it was as if he was walking uphill - Al-Hasan said: He leaned forward - and when he turned, he turned with his whole body.
