Who is the man whom the Messenger of Allah saw swaggering with his sword, and told him that he was one of the people of Hellfire?

We have not come across any report stating that the Prophet, peace and blessings be upon him, said of a man who swaggered between the ranks that he was among the people of Hellfire. Perhaps the questioner confused this with the story of Abu Dujanah, may Allah be pleased with him, on the day of Uhud, when he swaggered in his walk, and the Prophet, peace and blessings be upon him, said: "Indeed, it is a walk that Allah detests, except in this situation." And the story of the man who fought valiantly in battle, then the Prophet, peace and blessings be upon him, informed that he was among the people of Hellfire, as he committed suicide after being wounded.
