It is narrated from Hazrat Abu Barzah Aslami (may Allah be pleased with him) that once we were on a journey with the Prophet (peace and blessings of Allah be upon him). The Prophet (peace be upon him) heard the voices of two men who were singing, and the first was responding to the second (supporting him), and he was saying: "May the bones of my dear friend always shine; he wrapped up the battle before it became prolonged so that he could find a grave." The Prophet (peace be upon him) said: "Look, who are these two?" People informed him that they were such and such persons. The Prophet (peace be upon him) said: "O Allah! Send punishment upon them and hurl them into the fire of Hell."
