Musannaf Ibn Abi Shaybah 40474 — Reports on Uthman (may Allah be)

It is narrated from Muhammad (bin Sirin) that Sayyiduna Ali (may Allah be pleased with him) delivered a sermon in Basrah and said: By Allah, I did not kill Uthman, nor did I assist in his killing. When he came down from the pulpit, one of his companions said: Then what have you done? Now your companions are leaving you. So when Sayyiduna Ali returned to the pulpit, he said: Who is the one asking about the killing of Uthman? Indeed, Allah killed Uthman, and I will be with him (meaning, I too will be killed). Muhammad says: This is a Qurashi expression that has more than one aspect.
