Al-Tabari

Abū Jaʿfar Muḥammad ibn Jarīr ibn Yazīd al-Ṭabarī (Arabic: أَبُو جَعْفَر مُحَمَّد بْن جَرِير بْن يَزِيد ٱلطَّبَرِيّ; 839–923 CE / 224–310 AH), commonly known as al-Ṭabarī (Arabic: ٱلطَّبَرِيّ), was a Sunni Muslim scholar, polymath, historian, exegete, jurist, and theologian from Amol, Tabaristan, now in present-day Iran. Among the most prominent figures of the Islamic Golden Age, al-Tabari is widely known for his historical works and expertise in Quranic exegesis, although he has also been described as "an impressively prolific polymath". He authored works on a diverse range of subjects, including world history, poetry, lexicography, grammar, ethics, mathematics, and medicine. Among his most famous and influential works are his Quranic commentary, Tafsir al-Tabari, and historical chronicle, Tarikh al-Tabari.

Al-Tabari followed the Shafi'i school for nearly a decade before he developed his own interpretation of Islamic jurisprudence. His understanding of it was both sophisticated and remarkably fluid, and, as such, he continued to develop his ideas and thoughts on juristic matters right until the end of his life.

Al-Tabari's school of jurisprudence "flourished among Sunni ulama for two centuries after his death", before it eventually became extinct. It was commonly designated as the Jariri school.
