Formation of the Four Schools of Islamic Law

Between 750-850 CE, four major Sunni schools of Islamic jurisprudence (madhahib) emerged and became formalized. Abu Hanifa (d. 767), Malik ibn Anas (d. 795), al-Shafi'i (d. 820), and Ahmad ibn Hanbal (d. 855) founded these schools, each developing distinct methodologies for deriving Islamic law from the Quran and Sunnah. The schools initially represented regional legal traditions from Kufa, Medina, and Baghdad, evolving from personal teachings into institutionalized systems. By the 12th century, these four schools gained universal recognition within Sunni Islam, establishing a framework for Islamic jurisprudence that continues to shape Muslim legal thought and practice.
