And in Rajab of this year: in Tabuk, Khalid ibn al-Walid may Allah be pleased with him captured Ukaydir, king of Dumah, so the Messenger of Allah ﷺ spared his blood and settled with him on the jizyah.
It means that Khalid ibn al-Walid was able to capture Ukaydir. Then he was not killed. Instead, the Prophet ﷺ accepted that he remain alive in exchange for peace and payment of the jizyah.

The leader of the expedition who captured Ukaydir and brought him to the Prophet ﷺ
Ukaydir of Dumah is Ukaydir ibn Abd al-Malik al-Kindi. He was a ruler, or king, over Dumah al-Jandal, an important oasis in northern Arabia near the route to ash-Sham, and he was a Christian. His story is mentioned in the context of the Expedition of Tabuk in 9 AH, when the Prophet ﷺ reached the borders of ash-Sham and began organizing relations with the powers and towns in the north between Arabia and the Romans (Byzantines). The Prophet ﷺ sent Khalid ibn al-Walid may Allah be pleased with him on a raid to Ukaydir and told him that he would find him hunting wild cattle. Khalid went until he found him outside his fortress as he had been told, captured him, and brought him to the Prophet ﷺ. Then the Prophet ﷺ made peace with him, spared his blood, wrote him a document, and accepted the jizyah from him. Dumah al-Jandal then entered the treaty system instead of military confrontation.
He accepted the peace settlement and the sparing of his blood
