Anyone taking up the post of a judge must be a Muslim, free, mature, sane, just a Faqih (learned scholar), and aware of how to apply the rules to the events. The person who takes up the judiciary of Mazaalim, in addition to the conditions mentioned must also be male and a Mujtahid (jurist), just like the Qadhi al-Qudhah (Supreme judge). This is because this post is in fact a combination of judicial and ruling responsibilities, for He judges over the ruler and executes the Shari’ah upon him. Therefore He must be male in addition to the other conditions for the judge post, one of which is to be a Faqih. Furthermore, He has to be a Mujtahid, because as part of the Mazaalim He may be required to look into whether the ruler has ruled by other than that which Allah has revealed, i.e. ruled by a law that has no Shar’a evidence to back it, or in case the evidence He used does not relate to the event. It is only the Mujtahid who can deal with such Mazlama. Therefore if He were not a Mujtahid, He would be judging on something He knows little about or has no knowledge at all, and that is forbidden. Therefore, in addition to the conditions of the ruler and those of the judge, He should also be a Mujtahid.
