Ad-Dawāsir
The Dawasir country lies along the valleys of southern Najd, where streams descending from the western highlands join the broad Wadi ad-Dawasir. Wells, dams and cultivated plots mark the ways inhabitants used the water of its tributaries. The valley was once known as al-Aqiq, including Aqiq Banu Uqayl, before becoming associated with the Dawasir tribes. A fourteenth-century account names Rawa ibn Badran as a leader of the Dawasir.
