who was then a Zaydi, narrated, 'I went to Baghdad. While I was there, I saw the people congratulating each other all of a sudden, exchanging honourable greetings and standing up. I asked, 'What is this?' They replied, 'The son of al-Rida [has come].' Then I said, 'Indeed I must see him'. Then he appeared on a male or female donkey. I said, may the curse of Allah be upon the supporters of Imama who believe that Allah has made obedience to this [type of person] mandatory.' At that very moment, he turned to me and said, ?O sim b. 'Abd al-Rahman, Are we to follow a lone human from ourselves?! Indeed then we would be in error and madness. [He continued]: 'So I said to myself, 'A sorcerer, by Allah!', and he turned to me again, and said, Has the Reminder been cast upon him from among us? Rather he is a self-conceited liar. [He continued]: 'So I left, believing in Imama and bore witness that verily he is the proof of Allah on His creation and had faith in him.'
