Expedition of Khalid ibn al-Walid (2nd Dumatul Jandal)
Khalid ibn al-Walid invaded the city of Dumat Al-Jandal in April 631 AD, under the orders of Muhammad to retaliate for the killings of preachers that had previously been sent by him. He also ordered Khalid to destroy an idol that was worshipped by the Bani Kalb tribe.
This was the second time Khalid was sent on a military invasion to Dumat Al-Jandal. He was also sent to Dumatul Jandal in March 631 to invade the land of a Christian prince who ruled the area.
