A madhhab (Arabic: مذهب maḏhab, IPA: [ˈmaðhab], "way to act"; pl. مذاهب maḏāhib, [maˈðaːhɪb]) is a school of thought within fiqh (Islamic jurisprudence). In the first 150 years of Islam, there were numerous madhahib, most of which have become extinct or merged with other schools. The Amman Message, which was endorsed in 2005 by prominent Islamic scholars around the world, recognized four Sunni schools (Hanafi, Maliki, Shafi'i, Hanbali), two Shia schools (Ja'fari, Zaidi), the Ibadi school and the Zahiri school.[1]
Generally, Sunnis have a single preferred madhhab from region to region, but also believe that ijtihad must be exercised by the contemporary scholars capable of doing so. Most rely on taqlid, or acceptance of religious rulings and epistemology from a higher religious authority in deferring meanings of analysis and derivation of legal practices instead of relying on subjective readings.[24][25]
Experts and scholars of fiqh follow the usul (principles) of their own native madhhab, but they also study the usul, evidences, and opinions of other madhahib.
Sunni schools of jurisprudence are each named after the classical jurist who taught them. The four primary Sunni schools are the Hanafi, Shafi'i, Maliki and Hanbali rites. The Zahiri school remains in existence but outside of the mainstream, while the Jariri, Laythi, Awza'i and Thawri have become extinct.
The extant schools share most of their rulings, but differ on the particular practices which they may accept as authentic and the varying weights they give to analogical reason and pure reason.
The Ibadi school of Islam is named after Abd-Allah ibn Ibadh, though he is not necessarily the main figure of the school in the eyes of its adherents. Ibadism is distinct from both Sunni and Shi'ite Islam not only in terms of its jurisprudence, but also its core beliefs.
