6. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from al-Qasim ibn Yahya from his grandfather al-Hassan ibn Rashid from abu Basir who has said the following: “Abu ‘Abd Allah (a.s.), has said that ’Amir al-Mu’minin has said, ‘Do not use any ring other than what is made of silver, because the Messenger of Allah has said, “A hand which has a ring of iron does not become clean.’””
