Islom fiqhining turli mazhablari asoschilari, jumladan Abu Hanifa, Shofi'iy, Ahmad ibn Hanbal, Molik, Ja'far va boshqalar, Mujtahidi mutlaq hisoblanadi. Mujtahidlarning bu toifasi o'z usul al-fiqhini yaratib, hukmlarni (qoidalarni) chiqarishgan va boshqalarga bog'liq bo'lmay, mustaqil bo'lishgan.

The founders of various schools of Islamic Fiqh such as Abu Hanifah, Shafi‟i, Ahmad bin Hanbal, Malik, Jafar and others are considered Mujtahideen Mutlaq. This category of Mujtahideen set up their own Usul al-Fiqh to extract the Ahkam (rules) and are not restricted by others i.e. they are independent.
