When the Prophet and his followers returned to Medina, they arranged an expedition to exact retribution from the Ghassanite prince who had killed the Muslim envoy. A force of three thousand men, under the Prophet's adopted son Zaid, was sent to take reparation from the offending tribe.
Khalid Ibn Al-Walid was one of the generals chosen for the expedition. When they reached the neighborhood of Muta, a village to the southeast of the Dead Sea, they met with an overwhelming force of Arabs and Romans who were assembled to oppose them. The Muslims, however, resolved resolutely to push forward. Their courage was of no avail and they suffered great losses. In this battle Zaid and Jafar, a cousin of the Prophet, and several other notables were killed. Khalid Ibn Al-Walid, by a series of maneuvers, succeeded in drawing off the army and conducting it without further loses to Medina. A month later, however, 'Amr Ibn Al-As marched unopposed through the lands of the hostile tribes, received their submission, and restored the prestige of Islam on the Syrian frontier.
