Ali has narrated from his father from ‘Abd Allah ibn al-Mughirah from Jamil who has said the following: “Abu ‘Abd Allah (a.s.), has said, ‘If you are behind an Imam when he completes reading al-Hamd you say, ‘all praise belongs to Allah, Cherisher of the worlds,’ and do not say ‘Amen.’” (Ahadith 4-5 are best explained in the form of fatwa.) حسن - Allamah Baqir al-Majlisi (Mirʾāt al-ʿUqūl fī Sharḥ Akhbār Āl al-Rasūl (15/108))
