One of them is Abu Tahir Muhammad Ibne Ali Ibne Bilal. His story and what happened between him and Abu Ja’far Muhammad Ibne Uthman Amari,may Allah lighten his visage, is well-known. He seized the assets of the Imam, which were in his hands and refused to deliver them, and claimed that he is the representative. the congregation turned away from him and beseeched damnation for him and the famous letter came from the Master of the Age (a.s.).
Abu Ghalib Zurari says, Abul Hasan Muhammad Ibne Muhammad Ibne Yahya Maadhi said: One of our men followed Abu Tahir Ibne Bilal after the dispute had occurred. Then he turned away from him and returned to our congregation. I asked him about the reason.He said: One day, I was with Abu Tahir. His brother Abul Tayyib and Ibne Khizr and a group of his followers were present when a page entered and said: “Abu Ja’far Amari is on the door.” The party was terrified. I asked him what is happening here. He said to the page, “He comes in.” Abu Ja’far (a.s.)came in and the party and Abu Tahir stood for him. He sat at the presidency of the session and Abu Tahir sat humbly in front of him. Abu Ja’far (a.s.) remained silent until his awe made them silent. Then he said: “Abu Tahir, I call on you by the oath of Allah, did not the Master of the Age (a.s.) order you to deliver me the assets, which are in your hands?” He said: “By Allah, yes.” Abu Ja’far (a.s.) rose and left. A mortal silence had seized the party. When they regained their bearings, his brother Abul Tayyib said: “From where did you see the Master of the Age?” He replied, “Abu Ja’far (a.s.) took me to one of his houses. So, he appeared to me from the heights of his house and ordered me to carry the assets, which I am holding, to Abu Ja’far.”
Abul Tayyib said: “How did you know he was the Master of the Age?” “His awe and imposing charisma overwhelmed me and I was overtaken by such apprehension from him,” he said: “that I did not know he was the Master of the Age (a.s.).”
This was the reason of my disassociation from them.
