Yeyote anayeshika wadhifa wa uamuzi (ukadhi) lazima awe Mwislamu, awe huru, awe amefikia umri wa utu uzima, awe na akili timamu, awe Faqih (mwanachuoni mwenye elimu ya fiqhi), na ajue jinsi ya kutumia hukumu za sheria katika matukio yaliyopo. Mtu anayechukua wadhifa wa uamuzi wa Mazaalim, pamoja na masharti yaliyotajwa, lazima pia awe mwanaume na Mujtahid (mwanachuoni wa ijtihadi), kama ilivyo kwa Qadhi al-Qudhah (Jaji Mkuu). Hii ni kwa sababu wadhifa huu kwa kweli ni mchanganyiko wa majukumu ya uamuzi na ya utawala, kwani yeye hu hukumu juu ya mtawala na kutekeleza Shari'ah juu yake. Kwa hiyo, mbali na masharti mengine ya wadhifa wa uamuzi, lazima awe mwanaume, na mmoja wa masharti hayo ni kuwa Faqih. Zaidi ya hayo, lazima awe Mujtahid, kwa sababu kama sehemu ya Mazaalim anaweza kuhitajika kuchunguza iwapo mtawala ametawala kwa kutumia kisichokuwa alichoteremsha Allah, yaani kwa kutumia sheria isiyo na dalili ya Kishari'ah inayoiunga mkono, au pale dalili aliyotumia hailingani na tukio husika. Ni Mujtahid tu anayeweza kushughulikia madhulumu kama hayo. Kwa hiyo, asipokuwa Mujtahid, atakuwa anahukumu juu ya jambo asilolijua vya kutosha au asilolijua kabisa, na hilo ni haramu. Basi, mbali na masharti ya mtawala na yale ya jaji, anapaswa pia kuwa Mujtahid.

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.
