Musannaf Ibn Abi Shaybah 32709 — Reports on talk about rulers

Hilal bin Yasaf narrates: The courier who brought al-Mukhtar's head to Sayyiduna Abdullah bin al-Zubayr (may Allah be pleased with him) told me: When I placed al-Mukhtar's head before him, he said: "Whatever Ka'b told me, I have seen it come true, except for this matter: he told me that a man of the tribe of Banu Thaqif would kill me. I think it is I who have killed that Thaqafi."
