Sayyiduna Anas bin Malik (may Allah be pleased with him) narrates: The Prophet Muhammad (peace and blessings be upon him) was neither very tall nor very short. He was neither extremely fair-skinned nor dark-complexioned. His hair was neither completely curly nor completely straight. Allah Almighty appointed him as a Prophet at the age of forty. He (peace be upon him) spent ten years in Makkah and ten years in Madinah. Allah Almighty caused him to pass away at the age of sixty. At that time, there were not even (i.e., there were less than) white hairs in his blessed head and blessed beard.
