Before arriving, Qa’qa divided his troops into several smaller groups and instructed them to appear on the battlefield one after the other, giving the impression that large reinforcements were arriving. Qa'qa was busy raising morale and arranging his companions to the place from where he parted from them in previous day. The Persian army's elephants were a serious obstacle for the Muslims. To solve this problem, Qa’qa resorted to an ingenious device. The camels in his army were disguised to look like weird monsters. These "monsters" were moved to the Sassanid front and, upon seeing them, the Sassanid horses turned and fled. With the disorganization of the Sassanid cavalry, the Persian infantry at the left and center became exposed and vulnerable. Saad ordered an all out attack by the Muslims.

At sunrise of 19 November 636, the fighting had ceased, but the battle was still inconclusive. Qa'qa, with the consent of Saad, was now acting as a field commander of the Muslim troops. He is reported to have addressed his men as follows: ""If we fight for an hour or so more, the enemy will be defeated. So, warriors of the Bani Tameem make one more attempt and victory will be yours.""

The Muslims' left center led by Qa’qa surged forward and attacked the Sassanid right center, followed by the general attack of the Muslims' corps. The Sassanids were taken by surprise at the resumption of battle. The Sassanids left wing and left center were pushed back. Qa’qa again led a group of Mubarizuns against the Sassanids' left center and by noon, he and his men were able to pierce through the Sassanid center.
