Musannaf Ibn Abi Shaybah 40497 — Reports on Uthman (may Allah be)

It is narrated from Muhammad (Ibn Sirin) that Sayyiduna Hudhayfah (may Allah be pleased with him) said at the time of the killing of Sayyiduna Uthman (may Allah be pleased with him): "O Allah, if the Arabs did well in martyring Sayyiduna Uthman, that is, for the sake of good, guidance and Your pleasure, then I am free of it and I have no share in it; and if the Arabs erred in martyring him, then You already know that I am free of it." Then he said: "Take a lesson from what I am saying to you. By Allah, if the Arabs did good in killing him, they will soon see its benefit, and if they erred in it, they will also see its bloody harm."
