Note 139 — Chapter X · CAMPAIGN OF KHALID IN IRAC. A.H. XII. A.D. 633.
Reading edition
So the ordinary narrative. But there is another account that Okeidar was sent a prisoner to Medîna; and being subsequently released by Omar, settled near Ain Tamar, at a place which, in memory of his former home, he named Dûma. The name may have given rise to the tradition; though, on the other hand, the execution of Okeidar is in keeping with Khâlid’s sanguinary character. For his first encounter with Khâlid, see Life of Mahomet, p. 458.
