Al-Bayruzan

Piruzan (Persian=پیروزان) or al-Bayruzan (Arabic=البیروزان), also known as al-Birazan and Beerzan (Berzn) was a commander in the Sassanid Persian army during the Arab invasions in 7th century Persia. "al-Birazan" is known for his role in the battle of Battle of al-Qādisiyyah where he was killed in a duel with the Muslim commander Al Qa’qa'.

Battle of al-Qa-disiyyah
At the Battle of al-Qādisiyyah al-Bayruzan commanded the rear guard of the Sassanian army.

According to Amr b. Shas al-Asadi, on the first day of the battle

A1-Bayruzan fled without protecting [his men]; he brought calamity upon his troops.

On the morning of the second day of the battle, upon reaching the battlefield with a group of ten soldiers before the rest of his troops, Qa’qa ibn Amr, an Arab commander, challenged al-Bayruzan's soldiers to individual combat. A commander named Dhu al-Hajib (also known as Bahman) accepted and was killed. Later in the day, after more of Qa’qa ibn Amr's soldiers had arrived, he made another challenge and this time killed al-Bayruzan.
