Anas ibn Malik said:
“Allah’s Messenger (Allah bless him and give him peace) was neither very tall of stature, nor short. His skin was neither pale white, nor tawny, and his hair was neither crisply curled, nor lank. Allah (Exalted is He) sent him [to serve as His Messenger] at the end of forty years of life, so he stayed in Mecca for ten years and in Medina for ten years, and Allah took him unto Himself at the end of sixty years, with fewer than twenty white hairs on his head and in his beard.”
