Abū Jaʿfar Muḥammad ibn Jarīr al-Ṭabarī (; , ) (224–310 AH; 839–923 AD) was a prominent and influential Persian scholar, historian and exegete of the Qur'an from Tabaristan, modern Mazandaran in Iran, who composed all his works in Arabic. Today, he is best known for his expertise in Islamic sciences (Qur'anic commentary and law) or history, but he has been described as "an impressively prolific polymath. He wrote on such subjects as poetry, lexicography, grammar, ethics, mathematics, and medicine."
