Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from al-Qasim ibn Yahya from his grandfather al-Hassan ibn Rashid from Muhammad ibn Muslim who has said the following: “Abu ‘Abd Allah (a.s.), has said that ’Amir al-Mu’minin has said, ‘You must try to sniff viola; the Messenger of Allah, O Allah, grant compensation to Muhammad and his family worthy of their services to Your cause, has said, “Had people known about what is in viola they would drink and slurp it.’””
