Khalifa Umar bin al-Khattab - Battle Of Sura And Deirkab

While the main Muslim army remained at Babylon, Zuhra was commanded by Sa'ad to pursue the Persians who had retreated from Babylon. The Muslim advance guard under Zuhra followed the Persians, and caught the Persian rear-guard at Sura. The Persian rear-guard deployed themselves for action and after a short clash their resistance broke down and they with drew to Deir Kab.

Zuhra next marched to Deir Kab. There was large concentration of Persian forces at Deir Kab commanded by the General Nakheerzan. The two sides deployed their forces for combat. Then the Persian commander Nakheerzan stepped forward to throw a challenge for a personal duel.

From the Muslim side Zubair bin Salim a lieutenant of Zuhra stepped forward to accept the duel. In an exciting duel, Nakheerzan was overthrown and killed. Then the battle began. For some time the Persians put up a stiff resistance, and all Muslim attacks were repulsed. Then by a flanking movement Jareer bin Abdullah was able to capture the bridge at the rear of the Persians. From there he raised the shout of "Allah-o-Akbar'. At this the Persians lost heart, and they withdrew in great disorder after suffering heavy losses. Deir Kab was occupied by the Muslims, and the people were afforded protection under the usual terms.
