So Yahya narrated the story, saying, “I went to the city, and inquired about him, and when people heard my inquisitive questions, out of fear for Ali, they all gathered in riot to reassure me that this man was one whose heart has abandoned this world for the after, was always part of the mosque, did not have a tendency to have worldly desires, and has always been there to help and improve their lives.
“They made me swear to be gentle, and I reassured them that I was not ordered to harm him, and that there is nothing wrong. Then I searched his home but did not find but copies of the Koran and prayers, and books of knowledge, And this made him grow in my eyes, and I assumed the service myself, and did well treating him kindly.”
“When I reached Baghdad, Isaac Bin Abraham Al-Taheri, the ruler of Baghdad, began saying to me: ‘O Yahya, This man is the son of the messenger of God, and Mutawakkil, of whom you know, if you instigate him, will order his execution. And if this happens, the Messenger of Allah will be your opponent until the Day of Resurrection’.
“I said to him: By God, I have not stood by him, except in all matters sponsoring.”

They found the Imam in a closed room, covered in a woolen sweater, sitting on the sand and gravel, praying to God, reciting verses from the Koran. They proceeded to carry him the way he was to Mutawakkil, and said to him: “we did not find anything in his house, and when we found him, he was reading the Koran facing the Qiblah”.
Mutawakkil was sitting at his bar, and when he saw the Imam, honored and praised him, and seated him at his side, and offered him the cup which was in his hand.
The Imam responded: “By God, my flesh and blood have never been intoxicated, so pardon me”, so he pardoned him and said to him: “Recite us some poetry”.
