'Aqiq Banū 'Uqayl

Aqiq Banu Uqayl is an old name for the valley later called Wadi ad-Dawasir, in southern Najd. Its name recalls the Banu Uqayl, among the peoples associated with the valley before the Dawasir became predominant. The broad watercourse gathers several tributaries, and its inhabitants built dams and dug wells to provide drinking water and irrigate their farms. Other old names included al-Aqiq and Aqiq Tamrah.
