Ali ibn Muhammad has narrated from Sahl ibn Ziyad from Ali ibn Mahziyar from Ali ibn Rashid who has said the following: “I said to abu Ja‘far (a.s.), ‘You have different friends, thus, I perform Salah (prayer) behind every one of them.’ The Imam said, ‘Do not perform Salah (prayer) behind anyone whom you cannot trust in matters of his religion.’ He then said, ‘I have many friends.’ I said, ‘You have many companions.’ He then immediately, before I could mention their names, said, ‘No, (do not mention their names).

Ali ibn Hadid requires you to do this. Is this what Ali ibn Hadid commands you to do?’ I replied, ‘Yes, that is correct.’” شهور - Allamah Baqir al-Majlisi (Mirʾāt al-ʿUqūl fī Sharḥ Akhbār Āl al-Rasūl (15/256))
