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.

Dawmat al-Jandal was one of the large commercial towns of Arabia, widely known for its rich and much-frequented market. It was also an important communication centre, a meeting point of routes from Central Arabia, Iraq and Syria. At about the time when Khalid ibn Walid set off from Yamamah for the invasion of Iraq, Abu Bakr had sent Iyad ibn Ghanm to capture Daumat-ul-Jandal and once again bring the northern tribes into submission. Iyad arrived at Daumat-ul-Jandal to find it strongly defended by the Kalb, a large Christian Arab tribe inhabiting this region and the eastern fringe of Syria.

He deployed his force against the southern face of the fort known as Marid, and the situation that now developed was, from the military point of view, absurd. The Christian Arabs considered themselves to be under siege, but the routes from the northern side of the fort were open. The Muslims, engaged closely against the fort, considered themselves so heavily committed that they could not break contact. According to early historians both sides were under siege! The operations considered mainly of archery and sallies by the garrison of the fort. This state of affairs continued for several weeks until both sides felt equally tired and equally hurt by the stalemate. Then one day a Muslim officer said to Iyad, In certain circumstances wisdom is better than a large army. Send to Khalid for help . Iyad agreed. He wrote Khalid ibn al-Walid a letter explaining the situation at Daumat-ul-Jandal and seeking his help.
