Musnad Abu Ya'la al-Mawsili 119:1

Muhammad ibn Abi Bakr al-Muqaddami narrated to us, al-Hasan ibn Du'amah narrated to us, Umar ibn Sharik narrated to us, from his father, from Anas, that the Prophet (peace and blessings of Allah be upon him) said: "Dye yourselves with henna, for it is pleasant in scent and calms dizziness." Abu Ya'la said: I do not know if this Sharik is Ibn Abi Namir or not.
