Battle of al-Qaryatayn was a minor battle between the Christian Ghassanid Arab allies of the Byzantine Empire, and the Rashidun Caliphate army. It was fought after Khalid ibn al-Walid had conquered Tadmur in Syria. His army marched to al-Qaryatayn, the inhabitants of which resisted the Muslim army. They were fought, defeated and plundered. This resulted in the conquest of Al-Qaryatayn by the Muslim forces.
