I visited Fadl b. Rabih and he was sitting on the roof. He said: Come to me. I went close that I was right next to him. He said: Look to the side of that house. I looked to where he pointed, then he asked me: What do you see in the house? I said: I see a thrown cloak. He said: Look closer. I gazed attentively and scrutinized my vision, and then I was certain. I said: A man in prostration. He said: Do you know him? I said: No. He said: This is your master. I said: Who is my master? He said: Are you fooling me? I said: I am not fooling you. I do not know a master. Then he said: This is Abu’l Ḥasan Musa b. Ja`far. I inspect him day and night, and I have not seen him at any time except in this state which I shall describe to you: He prays Fajr, and afterwards he follows that with worship for an hour after his prayer (ta`qib) till sunrise. He then bows down in a prostrates and remains in prostration till midday. Someone was appointed to him to check for midday; I do not know when the boy recognizes that the Sun has reached midday. Then, [the Imam] rises and begins his [Dhuhr] prayer, without renewing his ritual ablutions (wudu’), and by this I know that he has not slept during his prostration and did not drowse. He remains in this state [of worship] till he finishes the `Asr prayer. If he prays `Asr, he then bows in a prostration and remains in prostration until the Sun sets. When the Sun sets, he rises from prostration and prays Maghrib without renewing anything, and he remains in the state of prayer and worship until he prays the first night prayer (`Isha’). When he finishes all this, he breaks his fast on something roasted that is brought to him. He then renews his ablutions. After that, he rises and spends the whole night in worship until dawn. I do not know how the boy recognizes and tells that it is time for Fajr, that I see him [Imam Musa] rising for Fajr prayer. This has been his state since the time he was transferred to me. Then, I said: Fear Allah, and do not do something ill to him which might cause you to be deprived of grace. You know well that no one does harm to one of them [the Ahl al-Bayt] without their bounties vanishing. He said: They sent to me more than once commanding me to kill him but I did not answer them to this, and I made them know that I will not do this, and that even if they kill me I will not answer them to what they are asking me to do. After that, [the Imam] was transferred to Fadl b. Yaḥya al-Barmaki. He was imprisoned there for days, and Fadl b. Rabih used to send him a meal each night. He was the only one allowed to enter upon him, so [the Imam] did not eat and did not break his fast except on this meal which was sent to him. This condition remained for three days and nights. On the fourth night, a meal was presented to him by Fadl b. Yaḥya (not Fadl b. Rabih). He (as) raised his hands to the sky and said: O Lord! You know that if I ate this before this day, I would have been performing suicide by my own hands. He ate, and then he got sick. The next day he was sent a doctor to inspect the illness. The doctor said to him: How are you? He did not answer him. When the doctor insisted, he let out the palm of his hand and showed it to the doctor and said: This is my disease. There was a greenness in his hand which indicated that he was poisoned, and the poison had gathered in that point. The doctor left and he said to: By Allah, he knows what you did to him more than you do! Then, he (as) passed away.
