Allah's Messenger (ﷺ) was the handsomest of all the people, and had the best appearance. He was neither very tall nor short.
Sahih al-Bukhari Book 61, Hadith 58
← Previous Hadith Allah's Messenger (ﷺ) was neither very tall nor short, neither absolutely white nor deep brown. His hair was neither curly nor lank. Allah sent him (as an Apostle) when he was forty years old. Afterwards he resided in Mecca for ten years and in Medina for ten more years. When Allah took him unto Him, there was scarcely twenty white hairs in his head and beard.

Sahih al-Bukhari Book 61, Hadith 57 Next Hadith → I asked Anas, "Did the Prophet (ﷺ) use to dye (his) hair?" He said, "No, for there were only a few white hairs on his temples."
