Awn bin Muhammad Hanafi narrates from his father, and he from his grandfather, Sayyiduna Ali bin Abi Talib (may Allah be pleased with him), that the Messenger of Allah (peace and blessings be upon him) said: "Make it a habit to use antimony (ithmid) kohl, for it grows hair, removes eye discharge (and stickiness), and brightens the eyesight."
