Battle of al-Qādisiyyah
After his victory at the Battle of al-Qādisiyyah in the summer of 636 AD, Saʿd ibn Abī Waqqās divided his army into five forces for the advance on Ctesiphon; they were commanded by Zuhra ibn al-Ḥawiyya, ʿAbdullah ibn al-Mutʼim, Shurḥabīl ibn as-Simt, Khālid ibn ʿUrfatah and Hāshim bin ʿUtba. The force under Zuhra met with some resistance at Burs, but this was soon overcome after he defeated Busbuhra, the garrison commander, in single combat.
