Mu'jam Kabir Tabarani 113 — Masruq met al-Ashtar, and Masruq said

Al-Sha'bi said: Masruq met al-Ashtar, and Masruq said to al-Ashtar: "Did you kill Uthman?" He said: Yes. Masruq said: "Listen, by Allah! You killed him while he was one who fasted much and stood much in prayer." The narrator said: Al-Ashtar went and informed Sayyiduna Ammar (may Allah be pleased with him), so Ammar came to Masruq and said: By Allah! Ammar was to be flogged, Abu Dharr was to be exiled, and the hima (reserved pasture) was to be guarded, and you say that we killed him while he fasted much and prayed much! Masruq said to him: "By Allah! You did neither of two things: you did not punish with the like of what you were punished with, nor did you show patience, though patience is indeed better for those who are patient." The narrator said: It was as though Masruq had stuffed a stone into Ammar's mouth. Al-Sha'bi further said: "No woman of Hamdan (tribe) ever gave birth to anyone like Masruq."
