Anas told that God’s Messenger sent Khalid b. al-Walid to Ukaidir of Duma,* and when they seized him and brought him he spared his life and made peace with him on condition that he should pay jizya. *Duma was a fortress-near Tabuk. Ukaidir was a Christian. The incident took place in the year 9 A.H during the expedition to Tabuk. Abu Dawud transmitted it.
