An-Numan ibn Muqarrin (النعمان بن مقرن) (d. December 641) was a companion of Muhammad. He was the leader of the tribe of Banu Muzaynah who lived close to Yathrib. He was also the son Ubaid bin Aus, an Ansar of Medina. Ubaid participated in the Battle of Badr, where he captured four men and tied them in one chain. For this act of binding, Muhammad nicknamed him Mugarrin, the Binder.
During the Caliphate of Abu Bakr and UmarEdit
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, Noman 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.
