But, for a brief period, he and other Tamim joined the force of false prophetess Sajah bint al-Harith before she was subdued during Ridda wars later on he carried successful military career under Khalid bin Walid suppressing another false prophet Tulayha in the Battle of Buzakha. after the Ridda wars has been ended he continued to follow Khalid's campaign to Syria and Iraq.Battle of Chains

Battle of Yarmouk

The Caliph Umar ibn al-Khattāb sent Al-Qa'qa' ibn 'Amr to take part in the battle of Qadisiyya. On 17 November 636, his units reached the battlefield at noon. 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. After the Persian army was routed Qa’qa ibn Amr went into pursuit and killed the Persian general Bahman, who commanded the Sasanian army at the Battle of the Bridge.When the battle resumed on 18 November 636, al-Qa'qa' led a vanguard cavalry of three hundred accompanied by Qays bin Hazim who led the Hashim tribe kinsmen who came from Syria together with local Iraqi tribal warriors. This time they were involved in melee combat against the Sassanid elephant corps. The Muslim cavalry blinded the elephants and severed their trunks with spears and other melee weapons while the Muslim archers struck down the elephant riders. The situation became dire for the Muslims later on that day, despite having already annihilated the elephant corps, because the Sassanids fought even more ferociously, resulting in al-Qa'qa's fellow kinsmen, Khalid bin Yamar al-Tamimi, being killed in the night. Consequently, al-Qa'qa' was tasked with the initiative of reinvigorating the Muslim army.
At sunrise of 19 November 636, the fighting had ceased, but the battle was still inconclusive. Al-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:
The Muslims' left center led by al-Qa’qa' surged forward and attacked the Sassanid right center, followed by the general attack of the Muslim corps. The Sassanids were taken by surprise at the resumption of battle. The Sassanids' left wing and left center were pushed back. Al-Qa’qa' again led a group of Mubarizun against the Sassanids' left center and by noon, he and his men were able to pierce through the Sassanid center.
Battle of Jalula
During the Battle of Jalula Mihran engaged his troops in an open battlefield, Hashim ibn Utbah decided to carry out his maneuver. He dispatched a strong cavalry regiment under one of his most illustrious cavalry commanders; Qaqa ibn Amr to capture the bridge over the entrenchments. The bridge was not heavily guarded as virtually all the Persian troops available were used to assault Muslim army's main rank. Qaqa maneuvered around Persian right flank quickly captured the bridge at their rear. The news of a strong Muslim cavalry detachment in their rear was a serious setback to Persian morale. Hashim launched a frontal attack with Muslim infantry while Qaqa stuck at Persian rear with his cavalry. Thus resulted the Sassanid Army trapped and routed in result.After the campaign in Jalula was ended he stayed and held a military post for a while in Kufa.
