A cikin tarihin Daular Musulunci, an shahara da adalci wajen gudanar da mulki, da kuma iyawarta na kare haqqoqin mutane, kuma haka lamarin yake a dukkan fannonin rayuwa, tun daga na kai har zuwa na siyasa.

In the history of the Islamic State, it was famous for its administration of justice, and its ability to protect the rights of the people, and this was the case in all the different fields of life, from personal to political.

Akwai mutum biyu da ke da alhakin aiwatar da Musulunci ta wannan hanya - Khalifa da alƙali (qadi). Khalifa yana aiwatar da dokokin Musulunci kuma yana tabbatar da su a kan mutane, yayin da alƙali kuma yake fitar da hukunce-hukuncen Musulunci ga yanayi daban-daban daga tushensu (watau Alƙur'ani, Sunnah, da abin da ya samo asali daga gare su) kuma yana gabatar da su don a aiwatar da su.

There are two people who are responsible for the implementation of Islam in such a manner - the Khaleefah and the qadi (judge). The Khaleefah executes the Islamic rules and implements them over the people, while the judge derives the Islamic verdicts for the different situations from their sources (i.e. the Qur’an, the Sunnah, and whatever derives from them) and presents them for application.

Saboda haka, shari'a (ɗaukar hukunci) na ɗaya daga cikin ginshiƙan asali na Daular Musulunci, kuma tsarin mulki yana dogara a kanta wajen aiwatar da Musulunci a rayuwar siyasa. Koyaushe akwai shari'a a cikin Daular Musulunci wadda ke gudanar da adalci, da alƙalai waɗanda ke yanke hukunci tsakanin mutane don tabbatar da cewa ana bin Musulunci a koyaushe.

Accordingly, the judiciary is one of the fundamental pillars of the Islamic State and it is upon this that the ruling system depends for the implementation of Islam in the political life. There has always been in the Islamic State a judiciary which administers justice, and judges who would judge between the people to ensure that Islam was constantly adhered to.

Wannan tsarin shari'a ba wani abu ba ne baƙo ga Musulunci; haƙiƙa yana samo asali ne daga aqidar Musulunci kuma yana zama wani sashe ba makawa na tafarkin rayuwar Musulunci, yana kuma cika sauran tsarin Musulunci, kamar tsarin tattalin arziki (Iqtisad) da tsarin ibada (Ibadat), har ya zama wani cikakken tsari mai aiki yadda ya kamata.

This system of judiciary is nothing alien to Islam; indeed it derives from the Islamic ‘aqeedah and forms an integrated part of the Islamic way of life, complementing the other Islamic systems, like the Economic (Iqtisad) and Ritual (Ibadat) systems, making a perfectly functioning whole.
