Sayyiduna Jabir bin Abdullah (may Allah be pleased with them both) said: Abu Quhafah was brought to the Messenger of Allah (peace and blessings be upon him), and his head and beard were as though they were white grass, so the Messenger of Allah (peace and blessings be upon him) said: "Take him to one of his womenfolk so that they may dye it." The narrator said: So they took him and they dyed it red.
