Haqq bait al-mal
Definition of "Haqq bait al-mal"
Lit: What is due to the state treasury. Tech: It refers to the taxation system in Ummayyad Iraq (AD 661–750) in which the tiller held the land under more than one lord, that is, the local feudal lord and the state. So the term haqq bait al mal was used in distinction with haqq al-dihqan, which meant what was due to the local feudal lord.
