Daumatul Jandal. Daumatul Jandal, the present day Al-Jauf, was in the time of Abu Bakr, a place of great strategic importance. It lay at the border of Iraq and Syria, and was the meeting place of the routes from Central Arabia, Iraq and Syria. In the strategy for the defenses of Arabia, Daumatul Jandal was a key point, and even the Holy Prophet was conscious of the importance of Daumatul Jandal.

Akeider. When in 630 C.E., the Holy Prophet undertook a campaign to Tabuk, Khalid was directed to lead a campaign to Daumatul Jandal. Khalid succeeded in his mission, and Akeider the Christian Arab ruler of Daumatul Jandal was taken captive. Akeider paid a heavy ransom, and on agreeing to pay an annual tribute, he was restored to his principality.

'Ayad bin Ghanam. After the death of the Holy Prophet, Akeider broke the pact with the Muslims, and defaulted in the payment of the tribute. Abu Bakr sent a column under 'Ayad bin Ghanam to capture Daumatul Jandal. 'Ayad laid a siege to Daumatul Jandal, but failed to capture it. The siege lasted for over a year, but still the resistance of the defenders was not broken. Many Christian Arabs driven from Iraq as a result of the operations of Khalid found refuge at Daumatul Jandal, and that created further difficulties for 'Ayad.

March of Khalid to Daumatul Jandal. At this critical juncture, 'Ayad wrote to Khalid to come to his help. Abu Bakr also asked Khalid to go to the help of 'Ayad. Khalid received the call for help when he was at 'Ein-at-Tamr. Khalid decided to go in for the help of 'Ayad forthwith. Leaving a garrison at 'Ein-at-Tamr, Khalid marched on with his main force to the relief of Daumatul Jandal. Khalid covered the journey of three hundred miles to Daumatual Jandal in ten days.

The battle of Daumatul Jandal. The Christian Arab forces at Daumatul Jandal were led by two chiefs, namely Akeider and Judi bin Rabee'a. Akeider, who had personal experience of the prowess of Khalid, was unnerved when he came to know that Khalid had arrived for the help of 'Ayad. He advised the Christian Arabs to make peace with Khalid. His advice was, however, not accepted by his people, who decided to fight. Thereupon 'Akeider withdrew from Daumatul Jandal, and set off on the road to Jordan. He was soon overtaken by a detachment of Khalid's cavalry. Accounts differ as to the fade of Ukeider. According to one account, when Ukeider was presented before Khalid, he ordered his execution, as he had broken his oath of allegiance. According to another account, Ukeider was sent to Madina, where he repented and was granted amnesty by Abu Bakr.

Thereafter, Khalid pressed the siege of Daumatul Jandal. The Christian Arabs under Judi bin Rabee'a offered resistance, but they could not hold on for long. Daumatui Jandal fell in the last week of August 633 C E. Over two thousand Christian Arabs were killed in the battle of Daumatul Jandal. Judi bin Rabaceia was captured alive. The people of Daumatul Jandal were offered amnesty on their agreeing to pay Jizya. Immense booty fell to the share of the Muslims. Judi bin Rabee'a had a beautiful daughter who was among the captives. She was a typical beauty. When Khalid saw her, he felt attracted and married.

Reaction of Yadrat Abu Bakr. When the news of the fall of Daumatul Jandal were communicated to Abu Bakr at Madina, he felt very happy. He felt proud of the exploits of Khalid, who had succeeded where others had failed. When the Caliph was told that Khalid had married Bint Judi, he merely smiled and said: "Great men have their eccentricities and Khalid, a great General, has a soft corner in his heart for beautiful women. He is the victor of Daumatul Jandal, and he may very well have Bint Judi as his prize, if that is his pleasure."
