Sayyiduna Arfajah bin As'ad (may Allah be pleased with him) said that his nose was cut off on the day of al-Kulab in the time of Ignorance (Jahiliyyah), so he had a nose made of silver. Then it began to give off a foul smell, so he (peace and blessings be upon him) "permitted him to have a nose made of gold."
