In the name of Allah the Most Beneficent and Merciful.
The beloved Prophet of Allah is the most handsome person ever created by Allah. The detailed explanation of his physical characteristics are detailed in the Shama`il of Imam Tirmidhi and As Shifa of Qadi Ayad (May Allah shower His mercy upon them both). Here is a Hadith describing the Messenger of Allah (May Allah bless him and grant him peace):
“He had the most radiant of colouring, deep black eyes which were wide set and had a sort of red tint in to them, long eyelashes, a bright complexion, an aquiline nose and a gap between his front teeth. His face was round with a wide brow and he had a thick beard which reached his chest. His chest and abdomen were of equal size. He was broad chested with broad shoulders. He had large bones, large arms, thick palms and soles, long fingers, fair skin and fine hair from the chest to the navel. He was neither tall nor short, but between the two. In spite of that, no tall person who walked with the Prophet seemed taller than him. His hair was neither curly nor straight. When he laughed and his teeth showed, it was like a flash of lightning or they seemed as white as hailstones. When he spoke it was like issuing from between his teeth. He had a well formed neck, neither broad nor fat. He had a compact body which was not fleshy.

Of course Allah knows best
