Shafi'i is one of the four major schools of Islamic jurisprudence, known as madhhabs. Founded by the scholar Imam al-Shafi'i in the 9th century, it emphasizes the importance of the Qur'an and Hadith as primary sources of law, along with consensus and analogy. The Shafi'i school is particularly influential in regions such as Southeast Asia, East Africa, and parts of the Middle East. It is recognized for its systematic approach to legal reasoning and its detailed methodology in deriving rulings, making it a significant tradition within Islamic law.
