The Book of the Judiciary
Chapter: Legal Rulings Concerning the Judiciary in Islam
Shaykh al-Islām Ibn Taymiyyah said: “It is obligatory to regard holding judicial office as a form of religion and a means of drawing closer to Allah, for it ranks among the finest acts of devotion. What has corrupted most people is their pursuit of prestige and wealth through it.”
The basis for this comes from the Quran, the Sunnah, and scholarly consensus. The Exalted says, “And judge between them by what Allah has revealed” (4:105), and He says, “O David, We have made you a vicegerent on earth; so judge between the people in truth” (38:26).
The Prophet—may Allah bless him and grant him peace—undertook the task himself, and he appointed judges in the regions that came under Muslim rule. His successors after him did the same. The Muslims unanimously agree that judges must be appointed to settle disputes among the people.
Linguistically, qaḍāʾ (judgment) means to perfect a matter and bring it to completion, as in the verse: “He completed them as seven heavens in two days” (41:12). In technical usage it refers to clarifying the sharʿī ruling, enforcing it, and resolving conflicts.
