When Dawud b. Ali [the governor of Madina] arrested al-Mualla b. Khunays, imprisoned him, and wanted to kill him – Mualla b. Khunays said to him: take me out to the people first, for I have a lot of debts and wealth which I want to declare, so he took him out to the market. When the people had gathered he [Mualla] said: O people, I am Mualla b. Khunays, whoever knows me has known me. I bear witness that what I leave of wealth, or debt, or slave-girl, or house, or less or more, then it is is for Ja`far b. Muhammad عليه السلام. He [al-Misma`i] said: then Dawud’s head of security struck him and killed him. When the news reached Aba Abdillah عليه السلام he came out dragging his cloak [on the ground – in his hurry] until he entered upon Dawud b. Ali with his son Ismail behind him and said: Dawud you killed my Mawla [client] and usurped my property?! He said: I did not kill him nor have I taken your property. He said: By Allah I am going to pray to Allah against the one who killed my Mawla and took my property! He [Dawud] said: I did not kill him – it was the head of my guards. He [the Imam] said: by your permission or without? He [Dawud] said: without my permission. He [al-Sadiq] said: O Ismail have your way with him! he [al-Mismai] said: so Ismail came out with a sword and killed him in his seating place. Hammad from al-Mismai from Muattib who said: Abu Abdillah عليه السلام remained standing in worship and in prostration the whole night. I heard him calling out near the end of the night whilst in prostration: O Allah, I ask you by your irrepressible strength, and your over-powering awe, and by your might in the face of which your creatures are abased, that you bless Muhammad and the family of Muhammad and that you take him this moment! He [Muattib] said: by Allah he [the Imam] had not raised his head from the prostration when we heard a cry and they said Dawud b. Ali has died. Abu Abdillah عليه السلام said: I supplicated against him to Allah with a supplication due to which Allah sent him an angel who struck his head with a hammer and caused his bladder to split.
