The Battle of Ayn al-Tamr (Arabic: معركة عين التمر) took place in modern-day Iraq (Mesopotamia) between the early Muslim Arab forces and the Sassanians along with their Arab Christian auxiliary forces. Ayn al-Tamr is located west of Anbar and was a frontier post which had been established to aid the Sassanids. The Muslims under Khalid ibn al-Walid's command soundly defeated the Sassanian auxiliary force, which included large numbers of non-Muslim Arabs who broke earlier covenants with the Muslims. According to William Muir, Khalid ibn al-Walid captured the Arab Christian commander, Aqqa ibn Qays ibn Bashir, with his own hands, which matched the accounts of both Ibn Atheer in his Usd al-ghabah fi marifat al-Saḥabah, and Tabari in his Tarikh.
