Muta (Moslem Invasion of Syria).
Fought 629, between the Moslems, under Zaid, and the troops of the Emperor Heraclius. Zaid was slain, and so successively were Jaafar and Abdallah, who followed him in the command, but the banner of the prophet was then raised by Khaled, who succeeded in repulsing the onslaught of the Imperial troops, and on the following day led the Moslems undefeated from the field. This is the first battle between the Mohammedan Arabs and a foreign enemy.
