After a Muslim victory in the Battle of al-Qādisiyyah, the Caliph Umar ruled that it was time to conquer the Sasanian Empire's capital of Ctesiphon.
Zuhra ibn Al-Hawiyya's military body left in advance and occupied Najaf, where he expected the rest of the troops to reach him.
The next step was Babylon, on the opposite bank of the Euphrates, a fortified city where it was known there was a large concentration of Sassanian forces.
While the bulk of the Muslims stationed at Babylon, Zuhra received from Sa`d ibn Abī Waqqās the order of chasing the Sasanians who had withdrawn from the city before they could concentrate somewhere else and oppose a new resistance.
