H 181 - Saad bin Abdullah Ashari said: I heard Ahmad bin Ubaidullah bin Khaqan – and he was the official of the ruler in Qom – say in a lengthy traditions, which we have condensed: When Abu Muhammad, Hasan Ibn Ali عليه السلام fell sick, he sent his men to my father and informed about the illness of Ibn Ridha. Immediately, he mounted a horse and moved towards Darul Khilafa. Then He came back hurriedly, accompanied by five reliable servants of the master of faithful. One of them was Nahrir. He ordered the servants to keep a vigil on the house of Hasan bin Ali and gather information about him from time to time. He called a group of physicians and asked them to visit him regularly. After two days, a person informed that Imam became very weak. My father started out to meet him and stayed with him till morning and then ordered his servants to stay with him. Then he called the chief justice and ordered him to select ten such persons from the community, who were known for their honesty and trustworthiness. The selected persons were thus sent to the house of (Imam) Hasan. They were ordered to stay there day and night till his demise. After a few days of the month of Rabi I, 260 A.H. passed away, the news spread in entire Samarrah that Ibn Ridha has passed away. Then he made preparations for the rites of Imam. He closed all the markets. My father, people of Bani Hashim, soldiers, secretaries and other people attended his funeral. The caliph asked Abu Isa Ibn Mutawakkil to offer the funeral prayer. The coffin was prepared and Abu Isa moved near it and removed the cloth off the face of Imam and addressed the people, “This is Hasan bin Ali bin Muhammad bin Ridha, who died a natural death and the servants of the master of faithful, and so-and-so judges are witness to it. Then he covered his face and stood up to offer the funeral prayer. He recited five Takbirs and the bier was ordered to be lifted. The bier was taken from his house and the Imam was buried near the grave of his father.
