An-Numan had several brothers, and all of them were accomplished soldiers. During the caliphate of Abu Bakr (r. 632–634), An-Numan and his family played a major role in putting an end to the apostasy wars. They fought under Khalid bin Waleed in the wars in Iraq, and later An-Numan fought under Sad Ibn Abi Waqqas. After the battle of Kaskar, Numan was appointed the administrator of the Kaskar district.

An-Numan was unhappy with the civil appointment and wrote to the caliph Umar ibn al-Khattab (r. 634–644) requesting active service. In the campaign against the Persians concentrated at Nihawand, Umar appointed An-Numan as the commander of the Muslim army. He was killed during the second phase of the Battle of Nihawānd on the third week of December 641.^[1]
