A Commander at the Battle of Yarmuk

In the Battle of Yarmuk in 15 AH, Hazrat Abu Ubaidah (ra) and Hazrat Mu‘az (ra) bin Jabal were appointed commanders on the right flank of the army. The Christians attacked with such intensity that the right flank of the army broke away from the rest of the army and consequently the soldiers became dispersed. Upon witnessing these circumstances, Hazrat Mu‘az (ra) bin Jabal displayed great courage and remained resolute. He stepped down from his horse and said that he would now fight on foot and if there was anyone who could do justice by fighting on a horse, then his horse was at their service. Hazrat Mu‘az (ra) bin Jabal’s son was also present in the battlefield and he said, “I shall do justice to it because I can fight better on horse” And so, both father and son, penetrated into the Byzantine forces and fought so valiantly that the Muslims who had initially lost their footing were now able to regroup and thus by defeating the enemy, their state of fear was transformed into victory for the Muslims.
