The Battle of Daumat-ul-jandal took place between Muslims and Rebel Arab tribes in August 633 AD. This was a part of the Riddah wars. Daumat ul jandal was given to Iyad ibn Ghanm to crush the rebels, but he failed in doing so, and send for help to Khalid ibn Walid who was in Iraq in those days. Khalid went there and defeated the rebels.
