Al-Shafi'i (Arabic: الشَّافِعِيّ, romanized: al-Shāfiʿī; IPA: [a(l) ʃaːfiʕiː] ;767–820 CE) was a Muslim scholar, jurist, muhaddith, traditionist, theologian, ascetic, and eponym of the Shafi'i school of Sunni Islamic jurisprudence. He is known to be the first to write a book upon the principles of Islamic jurisprudence, having authored one of the earliest work on the subject: al-Risala. His legacy and teaching on the matter provided it with a systematic form, thereby "fundamentally influencing the succeeding generations which are under his direct and obvious impact," and "beginning a new phase of the development of legal theory." Born in Gaza, Palestine, to the Banu Muttalib clan of the Quraysh tribe, he relocated at the age of two and was raised in Mecca. He later resided in Medina, Yemen, Baghdad in Iraq, and Egypt, and also served as a judge for some time in Najran. Source: Wikipedia (en)
