Qatadah narrates from Sayyiduna Anas bin Malik (may Allah be pleased with him) that it is disliked for a man to pluck out the white hairs of his head and beard; and the Messenger of Allah (peace and blessings be upon him) did not use dye; only a few hairs of his (peace and blessings be upon him) chin, temples and head were white.
Sayyiduna Anas bin Malik (may Allah be pleased with him) says that the Prophet (peace and blessings be upon him) did not use dye.
