Al-Qa'qa'a ibn Amr at-Tamimi

Al-Qa'qa' ibn 'Amr was a man of Banu Tamim. He and his tribe converted to Islam during the  Year Of Delegation and became Sahabi.

Battle of al-Qādisiyyah
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. 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 Sassanid army at the Battle of the Bridge.
