A number of our people have narrated from Sahl ibn Ziyad and Ya’qub ibn Yazid from Muhammad ibn Dadhawayh who has said the following: “I once wrote to abu al-Hassan, asking him (the Imam) about drinking intoxicating liquor. He (the Imam) wrote back in answer, ‘A wine drinker is an unbeliever.’” شهور - Allamah Baqir al-Majlisi (Mirʾāt al-ʿUqūl fī Sharḥ Akhbār Āl al-Rasūl (2/262))
