The Book of Occultation — al-Ṭūsī · Hadith 547 (#Ḥadīth #2)
Chapter 42 | Emissaries condemned by the Imam
ومنهم علي بن أبي حمزة البطائني وزياد بن مروان القندي وعثمان بن عيسى الرواسي، كلهم كانوا وكلاء لابي الحسن موسى عليه السلام، وكان عندهم أموال جزيلة، فلما مضى أبوالحسن موسى عليه السلام وقفوا طمعا في الاموال، ودفعوا إمامة الرضا عليه السلام وجحدوه. وقد ذكرنا ذلك فيما مضى فلا نطول بإعادته.
Among them Ali bin Abi Hamza Bataini, Ziyad bin Marwan Qandi and Uthman Rawasi These three were representatives of Abul Hasan Musa bin Ja’far and were having a large amount of the Imam’s funds in their possession. When Imam Kadhim passed away, they, in greed of the Imam’s funds did not accept that he is martyred and did not believe in the Imamate of Imam Ridha as we mentioned previously and its repetition again would prolong the book unduly.
