Taj al-Din al-Subki

Abd al-Wahhab ibn Ali al-Subki (727–771 AH / 1327–1370 CE), known as Taj al-Din al-Subki, was a Syrian Shafi'i scholar and the son of Taqi al-Din al-Subki. He is best known for his encyclopedic Tabaqat al-Shafi'iyya al-Kubra (The Great Classes of Shafi'i Scholars), a monumental ten-volume biographical dictionary of Shafi'i scholars from the school's founding to his own time. This work remains the single most important reference for the history of the Shafi'i school. He also wrote Jam' al-Jawami' in usul al-fiqh, which became a standard advanced text in Islamic legal theory and is still studied today. He served as a judge and teacher in Damascus and Egypt.
