1. [1/-] Uyun Akhbar al-Ridha: From his father from Sa`d from Muhammad b. Isa from Ziyad b. Marwan al-Qandi who said: I entered to meet Abi Ibrahim عليه السلام and with him was his son Abu al-Hasan – he said to me: O Ziyad this is my son so and so – his letter is my letter, his words are my words, his messenger is my messenger and whatever he says then the decision is what he says.
