In Islam, Muhammad used Kohl and recommended others to use it because he believed that it was beneficial for the eyes based on the following saying by him: "One of the best kinds of Kohl that you use is Ithmid (antimony); it brightens the vision and makes the hair (eye-lashes) grow" and he "used to apply Kohl to his right eye three times, and to his left eye twice." It is used by many Muslim men today during Ramadan as a sign of devotion.
