The Messenger of Allah ﷺ was neither excessively tall nor noticeably short. He was neither pale white nor dark brown. His hair was neither tightly curled nor completely straight. Allah commissioned him as a prophet at the age of forty. He remained in Mecca for ten years and in Medina for another ten, and Allah took his soul at the age of sixty. There were not even twenty white hairs on his head and beard.

لم يكن رسول الله ﷺ بالطويل البائن ولا بالقصير المتردد ولا بالأبيض الأمهق ولا بالآدم وليس بالجعد القطط ولا بالسبط بعثه الله على رأس أربعين سنة فأقام بمكة عشر سنين وبالمدينة عشرا وتوفاه الله على رأس ستين سنة وليس في رأسه ولحيته عشرون شعرة بيضاء
