He had the most radiant coloring, deep black eyes which were wide set and had a sort of red tint 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 blessed teeth showed, it was like a flash of lighting or they seemed as white as hailstones. When he spoke, it was like light issuing from between his teeth. He had a well-formed neck, neither broad nor fat. He had a compact body which was not fleshy.
Al-Bara’ said, “I did not see anyone with a more beautiful lock of hair resting on a red robe than the Messenger of Allah .”
Abu Hurayra said, “I have not seen anything more beautiful than the Messenger of Allah . It was as if the sun was shining in his face. When he laughed, it reflected on the wall.”
Jabir ibn Samura was asked, ”Was his face like a sword?” He replied, “No, it was like the sun and the moon. It was round.” (In al-Bukhari and Muslim and elsewhere)
In her description, Umm Ma’bad said, “From afar, he was the most beautiful of people, and close up he was the most handsome.” (Al-Bayhaqi)
Ibn Abi Hala said, “His face shone like the full moon.”
At the end of his description, ‘Ali said, “Anyone who saw him suddenly was filled with awe of him. Those who kept his company loved him.”
All who described him said they had not see anyone like him either before or since.
