 8. Ali ibn Ibrahim has narrated from Yasir al-Khadim who has said the following. “When al-Ma’mun left Khurasan for Baghdad along with him came Fadl, Dhu al-Al-Ri’asatayn and we came out with abu al-Hassan  Fadl ibn Sahl had received a letter from his brother Hassan, while we were on our journey. Hassan had said in the letter, “I studied the Zodiac changes this year according to the astrological calculations. I found out in the month of so and so on a Wednesday you will feel the test of iron and fire. I urged you to go to a Turkish bath with al-Ma’mun and Imam Ridha  and perform phlebotomies and stain your hands with blood which, will help remove this misfortune from you. Fadl ibn Sahl wrote about it to al-Ma’mun requesting him to request His Holiness Imam Ali ibn Musar-Redha  to also join them on the appointed day. Al-Ma’mun informed the Holy Imam of the contents of that letter and demanded the consent of His Holiness. In reply to the caliph’s letter Imam al-Ridha  wrote, “I will not go to the Turkish bath tomorrow. You and Fadl also must not go there tomorrow.” He sent that letter to the Imam  twice. Abu al-Hassan  wrote to him, “O Amir al-Mu’minin, “I will not go to the Turkish bath. I have seen in a dream the Holy Prophet  enjoining me not to go to that Turkish bath. You and Fadl also must not go to the Turkish bath.” Al-Ma’mun replied the letter saying, “You have spoken the truth and so has the Messenger of Allah. I will not go to the Turkish bath tomorrow and Fadl knows best.” The narrator has said that Yasir said, “When the night fell al-Rida  told us to say, “We seek refuge in Allah against the misfortune in this night. We continued saying the expression. When al-Rida  prayed the Morning Prayer he asked me to climb at the roof and to listen if there is anything. When I climbed I heard a great deal of commotion and crying and it was increasing. We saw al-Ma’mun enter from the door that opened to his quarter from the quarter of abu al-Hassan  and he said, “My master, abu al-Hassan, may Allah grant you good reward for the death of Fadl. He refused to cancel his decision for the bath and he went to the Turkish bath. A group of people attacked him with swords and killed him. Three of the attackers were arrested and one of them was the son of his maternal uncle, the son of Dhul al-Qalamayn. He then said that the police and the guides and the people of Fadl present at the door of al-Ma’mun said, “He has murdered him.” They killed him. They meant al-Ma’mun thereby.” “We revenge him.” They set the door on fire.” Al-Ma’mun said to abu al-Hassan , “My master, please come out to them to calm them down and ask them to disperse.” The narrator has said that Yasir said, “Abu al-Hassan  rode and asked me to ride also. When we were out of the door of the house he looked at the people who were crowded. He made hand gestures to asked them to disperse.” Yasir has said, “People began to fall one on the other and to whoever, that he would make a hand gesture he would run and pass by.”
