Musnad Ahmad 25:1176

'Affan narrated to us, Wuhayb narrated to us, 'Abdullah ibn 'Uthman ibn Khuthaym narrated to us, from Sa'id ibn Jubayr, from Ibn 'Abbas, who said: The Messenger of Allah (peace and blessings of Allah be upon him) said: "Wear your white garments, for they are among the best of your garments, and shroud your dead in them. And indeed, among the best of your kohl is antimony (ithmid), for it clears the vision and makes the hair grow."
