Muʿjam al-Aḥādīth al-Muʿtabara 1, narration 121

Translation

1. [1/-] al-Kafi: From Muhammad b. Abdallah and Muhammad b. Yahya both from Abdallah b. Ja’far al-Himyari who said: We gathered – me and the Shaykh Abu 'Amr (al-'Amri) – may Allah have mercy on him – at Ahmad bin Ishaq’s, then Ahmad b. Ishaq signaled me to ask him (al-'Amri) about the Remnant (al-Mahdi), so I said to him: … and Abu Ali Ahmad b. Ishaq has relayed to me on the authority of Abi al-Hasan (al-Naqi) (AS), saying: I asked him and said: "Whom do I emulate or from whom do I take? And whose words do I accept?" So he said to him: "Al-'Amri is my Thiqa (trustee), so what he gives you on my behalf then his giving is truly on my behalf, and what he says to you on my behalf then his saying is truly on my behalf, so listen to him and obey him, for he is both Thiqa (trustworthy) and reliable." And Abu Ali also informed me that he had asked Abu Muhammad (al-Askari) (AS) about the same matter, so he said to him: "Al-'Amri and his son are both trustees, so what they give to you on my behalf then their giving is truly on my behalf, and what they say to you on my behalf then their saying is truly on my behalf, so listen to them and obey them, for they are both Thiqa trustworthy and reliable…"
