"The Mubarizun (Arabic: \u0645\u0628\u0627\u0631\u0632\u0648\u0646\u200E, \"Duelists\") formed a special unit of the Rashidun army. It was composed of the elite warriors, who were champion swordsmen, lancers and archers. In pre-Islamic Arab, Byzantine and Sassanian warfare, battles usually began with duels between the champion warriors of the opposing armies."@en .
