Madhhab

A madhhab (Arabic: مَذْهَب, meaning "way to act") is a school of thought in Islamic jurisprudence. The main Sunni madhhabs are the Hanafi, Maliki, Shafi'i, and Hanbali schools. These schools emerged during the ninth and tenth centuries CE, and by the twelfth century, nearly all Islamic jurists had aligned themselves with one of them. The four schools recognize each other as valid and have engaged in legal debate over the centuries. Their rulings, or fatwas, are followed across the Muslim world without strict regional boundaries, though each school became dominant in specific areas: the Maliki school in North and West Africa, the Hanafi school in South and Central Asia, the Shafi'i school in East Africa and Southeast Asia, and the Hanbali school in North and Central Arabia.

In the early centuries of Islam, several short-lived Sunni madhhabs also existed. The Zahiri school, now considered endangered, still influences legal thought. Shia legal schools developed along theological lines, producing the Ja'fari madhhab among Twelver Shias, as well as the Isma'ili and Zaydi madhhabs for Isma'ilis and Zaydis respectively. Their differences from Sunni schools are roughly comparable to the differences among Sunni schools themselves. The Ibadi legal school, distinct from both Sunni and Shia madhhabs, is predominant in Oman. Non-denominational Muslims, unlike Sunnis, Shias, and Ibadis, do not affiliate with any madhhab.

Modern transformations of Islamic legal institutions have deeply affected the madhhab system. As codified state laws spread across the Muslim world, the influence of madhhabs beyond personal ritual practice now depends on their status within each national legal system. State law codification often drew on rulings from multiple madhhabs, and legal professionals trained in modern law schools have largely replaced traditional ulama as interpreters of these laws. In the 20th century, some jurists began asserting their intellectual independence from traditional madhhabs. With the spread of Salafi influence and reformist currents, a handful of Salafi scholars have claimed independence from being strictly bound by the traditional legal mechanisms of the four schools. Still, the majority of Sunni scholarship continues to uphold the post-classical belief in rigorously adhering (taqlid) to one of the four schools in all legal details.

The Amman Message, endorsed in 2005 by prominent Islamic scholars worldwide, recognized four Sunni schools (Hanafi, Maliki, Shafi'i, Hanbali), two Shia schools (Ja'fari, Zaydi), the Ibadi school, and the Zahiri school. Schools of Islamic jurisprudence are located in countries including Pakistan, Iran, Bangladesh, India, Indonesia, Nigeria, Egypt, Turkey, Afghanistan, Kazakhstan, Russia, China, the Philippines, Algeria, Libya, and Saudi Arabia.

Early Islamic law emerged from a mix of administrative and community-based practices in conquered territories, shaped by Islamic religious and ethical principles. While retaining some pre-Islamic laws and customs and modifying others, this legal system aimed to establish norms of Islamic conduct and resolve community disputes. This gradual development took place within the cultural and political context of the era and region, amid retrospective constructs and traditions reflecting the understandings of the social fabric. It unfolded in learning circles where students and aspiring scholars gathered to acquire knowledge from a local master and deliberate on religious matters—circles that later became known as schools of law.

The Sunni tradition (Hanafi, Maliki, Shafi'i, Hanbali) provided broad jurisprudence in practical matters, but its legal framework developed under the shadow of the Umayyad and Abbasid state apparatuses, prioritizing political stability, communal cohesion, and a public law rooted in Qurayshi lineage. Conversely, Shia schools (Twelver, Zaidi, Ismaili) grounded both political and religious legitimacy in the theology of the Imamate, framing authority as an exclusive, divinely appointed right reserved for the infallible progeny of the Ahl al-Bayt. In radical opposition to both these lineage- and charisma-centered aristocracies, the Ibadi school—derived from the moderate wing of the Kharijite movement—rejected tribal and genealogical elitism, advocating for a merit-based, elective, and accountable model of public governance that eventually became predominant in Oman. Ultimately, each legal school developed its distinct scriptural canon, hadith collections, and hermeneutical methodologies primarily to substantiate and legitimize its underlying political philosophy and framework of authority.

According to John Burton, modern research shows that fiqh was first regionally organized, with considerable disagreement and variety of view. In the second century of Islam, schools of fiqh were noted for the loyalty of their jurists to the legal practices of their local communities, whether Mecca, Kufa, Basra, Syria, or elsewhere. Egypt's school in Fustat was a branch of Medina's school of law and followed such practices—up until the end of the 8th century—as basing a verdict on one single witness, not two, and the oath of the claimant. Its principal jurist in the second half of the 8th century was al-Layth b. Sa'd. Al-Shafiʽi wrote that every capital of the Muslims is a seat of learning whose people follow the opinion of one of their countrymen in most of his teachings. The real basis of legal doctrine in these ancient schools was rooted in local tradition and practice.
