 Muhammad also sent Khalid on an expedition to Dumatul Jandal, to attack the Christian Prince Ukaydir who lived in a castle there. This took place in March 631 AD, 9AH, 11th month of the Islamic Calendar. In this campaign, Khaled took the Prince hostage and threatened to kill him until the door of the castle was opened. Muhammad then later ransomed him in exchange for 2000 camels, 800 sheep, 400 sets of armour, 400 lances, and a pledge to pay Jizyah.
