Muwatta Malik #1796

Yahya related to me from Malik that Rabia ibn Abi Abd ar-Rahman heard Anas ibn Malik say, "The Messenger of Allah, may Allah bless him and grant him peace, was not excessively tall or short. He was not very pallid nor dark. He did not have curly hair or lank hair. Allah commissioned him at the age of forty. He stayed in Makka ten years and at Madina for ten years and Allah the Mighty, the Majestic made him die when he was sixty. There were not twenty white hairs in his hair or beard, may Allah bless him and grant him peace."
