It is permitted to appoint the judge, the Muhtasib (judge of public rights) and the Mazalim in a general capacity, to judge in all matters all over the State. It is also permitted to appoint them in a specific capacity, whether geographic or according to a certain type of judiciary. This would be in accordance with the action of the Messenger of Allah (pbuh). He (pbuh) appointed Ali Ibnu Abi Talib as judge over Yemen, and Mu’az Ibnu Jabal as judge over an area of Yemen, and He also appointed ‘Amru Ibn al-‘A‘as as judge in one specific matter.
