Ali has narrated from his father from Ibn Abi ‘Umayr from ibn ’Udhaynah from Zurarah who has said the following: “Abu Ja‘far (a.s.), has said, ‘The sermons and Friday Salah (prayer) are not valid without the presence of five people, the fifth of whom is the Imam.’” حسن - Allamah Baqir al-Majlisi (Mirʾāt al-ʿUqūl fī Sharḥ Akhbār Āl al-Rasūl (15/349))
