Ar-Rabb
Ar-Rabb was a stopping place on the route along the Euphrates between al-Anbar and Hit. Medieval accounts of the road place it seven farsakhs from al-Anbar and twelve from Hit, among the settlements and stations linking the cultivated lands of Iraq with the upper river. The surrounding country forms part of the dry plain west of the great rivers, where settlement followed the river and its channels rather than the open desert.
