Simak bin Harb (may Allah have mercy on him) narrates: It was asked from Sayyiduna Jabir bin Samurah (may Allah be pleased with him) whether there was old age (gray hair) in the blessed head of the Messenger of Allah (peace and blessings be upon him)? He replied: There was no sign of old age on the blessed head of the Prophet (peace and blessings be upon him) except for a few hairs at the place where the parting of the hair is made; when oil was applied, the oil would conceal them.
