It is narrated from ‘Ala bin Ziyad ‘Adawi that he said to Sayyiduna Anas bin Malik (may Allah be pleased with him): O Abu Hamzah! When the Messenger of Allah (peace and blessings be upon him) was sent as a Prophet, how old was he at that time? He said: Forty years. He asked: Then what happened? He said: Then he (peace and blessings be upon him) stayed in Makkah for ten years and in Madinah for ten years, thus his age became sixty years, then Allah Almighty caused him (peace and blessings be upon him) to pass away. He asked: In those days, what kind of age did the Messenger of Allah (peace and blessings be upon him) appear to be? He said: Like the most vigorous youth, the most handsome and well-built. He asked: O Abu Hamzah! Did you participate in jihad with the Noble Prophet (peace and blessings be upon him)? He said: Yes, I was with him (peace and blessings be upon him) at the Battle of Hunayn.
