4. [4/264] Rijal al-Kashshi: Muhammad b. Masud from al-Fadhl from Ibn Abi Umayr from Ibrahim b. Abd al-Hamid from Ismail b. Jabir who said: Abu Ishaq [al-Sadiq] arrived from Makkah and the killing of Mualla b. Khunays was mentioned to him. He [Ismail] said: So he stood up in anger – dragging his garment [on the ground i.e. moving in a hurry]. Ismail – his son – said to him: O father – where are you going? He said: even if it were a calamity [that be in front of me] – I would still head out towards it! so he went until he entered upon Dawud b. Ali [i.e. the Abbasid governor of Madina]. He [the Imam] said to him: O Dawud – you have committed a sin for which Allah will never forgive you! He [Dawud] said: and what is that sin? He said: you have killed a man from the people of Jannah – then he paused for a bit – then he added: if Allah wills. Dawud said to him: and you have also committed a sin for which Allah will never forgive you! He [the Imam] said: and what is that sin? He [Dawud] said: you married off your daughter to so and so – the Ummayad. He [the Imam] said: if I have married her off to so and so – the Umayyad – then the Messenger of Allah ﷺ had given in marriage to Uthman, and I have in the Messenger of Allah an example [to follow]. He [Dawud] said: it is not me who killed him. He [the Imam] said: then who killed him? He [Dawud] said: al-Sayrafi killed him. He [the Imam] said: then retaliate on our behalf over him. So when it was the morrow – he [Dawud] came to him [al-Sayrafi] first thing in the morning – took him and had him killed. He [al-Sayrafi] began to cry out [before his execution]: O slaves of Allah! they order me to kill people for them and then they kill me!
