3. [3/263] Rijal al-Kashshi: Hamduwayh from Muhammad b. Isa from Ibrahim b. Abd al-Hamid from al-Walid b. Sabih who said: Dawud b. Ali said to Abi Abdillah عليه السلام: I am not the one who killed him – that is Mualla [b. Khunays]. He [the Imam] said: then who killed him? he said: al-Sayrafi – who was the man in charge of his guards. He [the Imam] said: grant us retaliation. He [Dawud] said: I have. So when al-Sayrafi was taken and was about to be killed he began saying: O masses of the Muslims, they order me to kill people so I kill them for them then they kill me. al-Sayrafi was then executed.
