Abu Ja’far (a.s.) said, ‘So they think such people are unbelievers.’ The Imam then said to me, ‘Disbelief is before paganism.’ He (the Imam) then mentioned Satan when Allah told him to prostrate, and he refused to do so. The Imam said that disbelief is before al-Shirk (paganism and considering things as partners of Allah). Whoever boldly disobeys Allah and commits major sins is an unbeliever.

He has considered belief insignificant so he is an unbeliever.’” وثق كالصحيح - Allamah Baqir al-Majlisi (Mirʾāt al-ʿUqūl fī Sharḥ Akhbār Āl al-Rasūl (11/111))
