Sayyiduna Jabir bin Samurah رضي الله عنه narrates that the shins of the Noble Prophet صلى الله عليه وآله وسلم were proportionately slim in accordance with the rest of his body. The Prophet صلى الله عليه وآله وسلم did not laugh loudly; rather, he would only smile. When I looked at him صلى الله عليه وآله وسلم, it seemed as if he had applied kohl to his eyes, even though he صلى الله عليه وآله وسلم had not applied any kohl. (That is, the eyes of the Prophet صلى الله عليه وآله وسلم were naturally dark-lined.)
