Battle of Buzakha. When the Muslim army reached Buzakha, they were confronted by the forces of the apostate tribes. In spite of some defections, the forces of the confederate tribes were considerable in strength, and outnumbered the Muslim force. Khalid called upon Taleaha to submit to Islam, but he ridiculed the offer. Thereupon the two armies clashed. The Muslim forces were commanded by Khalid, while the forces of Taleaha were commanded by 'Uyaynah, the chief of Bani Fazara. The two armies were well matched, and the outcome of the battle seemed uncertain.

Taleaha retired to a place of safety, and pretended to await heavenly inspiration. Khalid increased his pressure and 'Uyaynah hard pressed waited on Taleaha to inquire whether he had received any message from the heavens about the outcome of the battle. Taleaha replied that the request made by him was under consideration in the heaven, and a reply was expected any moment. 'Uyaynah led a charge against the Muslim forces, but was beaten back with heavy losses. He again waited on Taleaha, and wanted to know whether any reply had come from the heavens. Taleaha said that God had spoken to him in the following terms: "Your hopes and that of Khalid shall remain at variance, and between you matters are so ordained that an event will take place which you will never forget." At this ambiguous message carrying no sense, 'Uyaynah realized that Taleaha was an imposter, and his cause was doomed to failure. He told Taleaha "Woe to you! I go." 'Uyaynah asked the men of his tribe to break camp and retreat to save themselves. With the withdrawal of 'Uyaynah and his men the tide of the battle was turned in favor of the Muslims. Khalid intensified the attack, and the battlefield came to be strewn with the dead bodies of the men of Taleaha. Finding resistance useless, Taleaha escaped with his wife to Syria. With the withdrawal of Taleaha the battle was over. The Muslims had won a significant victory. Most of the tribes surrendered and accepted Islam. Those who still remained opposed to Islam retreated and sought refuge further inland.

Sequel to the battle of Buzakha. Khalid made Buzakha his headquarters and re-organized the administration. He appointed his agents for the various districts. General amnesty was granted to those who re-entered the fold of Islam and expressed regret for their past behavior. Those who had perpetrated atrocities on the Muslims were apprehended and subjected to likewise atrocities. The vacillating tribes in the region who had been sitting on the fence, and had preferred to watch the course of events submitted to the authority of Madina, paid Zakat and were re-admitted to the fold of Islam. The chiefs of the tribes who surrendered were sent to Madina for presentation before Abu Bakr. Considerable booty captured from the battlefield was also sent to Madina. Abu Bakr treated such chiefs with due courtesy and kindness. Khalid submitted a detailed report to Abu Bakr about the operations at Buzakha. Abu Bakr approved of the action taken, and appreciated the services of Khalid and his men in strong terms.

Taleaha on escape from Buzakha sought refuge in Syria. When Syria was occupied by the Muslims, Taleaha accepted Islam again and his career as a false prophet came to an end. Later he joined the Muslim army and took conspicuous part in the battles of Qadsiya and Nehavand, during the caliphate of Umar.
