Hazrat Malik bin Aws bin Hammad Thani narrates that Hazrat Abu Dharr returned from Syria and entered the mosque. At that time, Hazrat Uthman was also in the mosque. He (Abu Dharr) said: "Peace be upon you." He (Uthman) replied: "And peace be upon you, O Abu Dharr, how are you?" He (Abu Dharr) said: "I am well. How are you, O Uthman?" He (Uthman) replied: "I am also well."
