Sayyiduna Abu Hurairah (may Allah be pleased with him) said: "I came to Sayyiduna Uthman (may Allah be pleased with him) on the day of the siege. I asked: O Commander of the Believers! Will you not fight?" He replied: "O Abu Hurairah! Do you wish to kill all the people and me?" I said: "No." He said: "If you kill one man, it is as if you have killed everyone."
