Abū ʿAbdullāh Muhammad ibn Idrīs al-Shafiʿī (Arabic: ابو عبدالله محمد بن إدريس الشافعيّ‎) was a Muslim jurist, who lived from 767 CE to 820 CE. He was active in juridical matters and his teaching eventually led to the Shafi'i school of fiqh (or Madh'hab) named after him. Hence he is often called Imam al-Shafi'i. He is considered the founder of Islamic jurisprudence.
