Allohning Elchisi ﷺ qozilarni tayinlar edi; u Aliyni Yaman ustiga qози etib tayinladi va unga qanday hukm qilish kerakligi haqida ko‘rsatma berib dedi: “Agar ikki tomon o‘rtasida nizo bo‘lib, sizning oldingizga kelsa, ikkinchi tomonning gapini eshitmaguningizcha ulardan birining foydasiga hukm chiqarmang.” U ﷺ, shuningdek, Abdulloh ibn Navfalni Madina ustiga qози etib tayinladi.

The Messenger of Allah (saw) used to appoint the judges; he appointed ‘Ali as judge over Yemen and he gave him instructions about how to judge by saying, “If two disputing persons came to you do not judge for either of them until you have heard what the other had to say.” He (saw) also appointed ‘Abdullah ibn Nawfal as judge over Madinah.

Biroq, barcha qozilar bir turdan emas edi, ularning yurisdiksiyasi esa ularga berilgan vazifalarga ko'ra turlicha edi. Ba'zi qozilar odamlar o'rtasidagi nizolar bilan shug'ullangan, boshqalari xalqning umumiy manfaatiga zarar yetkazadigan masalalarni hal qilgan, yana boshqalari esa xalq bilan ularning ustidan hokimlik qiluvchilar o'rtasidagi nizolar sohasi bilan shug'ullangan.

However, all the judges were not of one type, and the areas over which they had jurisdiction varied according to the roles they were allocated. Some judges were concerned with the disputes between the people, others with settling whatever harms the common interest of the people and others dealt with the area of disputes between the people and those who were in authority over them.
