Umayr bin Zawdi said: Sayyiduna Ali (may Allah be pleased with him) addressed the people and said: "O people! By Allah, if none were to enter Hell except the one who killed Uthman, I would not enter it; and if none were to enter Paradise except the one who killed Uthman, I would not enter it." The narrator said: When he came down from the pulpit, it was said to him: You have said something by which your companions have split away from you. So he addressed them again and said: "O people! Listen, Allah, the Mighty and Majestic, killed Uthman and I am with him." Hammad said: And Habib bin al-Shahid narrated to us from Muhammad bin Sirin, who said: It is a Qurayshi expression that has two meanings. Abu al-Qasim (Imam al-Tabarani, may Allah have mercy on him) said: It is as if he meant that Allah Almighty caused him to be killed and I too will be killed along with him, may Allah be pleased with them both.
