Shafi'i refers to one of the four major Sunni schools of Islamic jurisprudence, founded by the scholar Muhammad ibn Idris al-Shafi'i in the 9th century. This school emphasizes a systematic approach to interpreting Islamic law, combining the Quran, Hadith (sayings and actions of Prophet Muhammad), consensus (ijma), and analogy (qiyas). The Shafi'i school played a significant role in shaping Islamic legal thought and practice, particularly in regions where Islam spread.
