Abū Jaʿfar Muḥammad ibn Jarīr ibn Yazīd al-Ṭabarī (Arabic: أبو جعفر محمد بن جرير بن يزيد الطبري), also known as al-Tabari or in Persian as Tabari, 839–923 CE, was an influential Sunni scholar, historian and commentator on the Qur'an from Amol, Tabaristan (modern Mazandaran Province of Iran). Today, he is best known for his expertise in Qur'anic exegesis (tafsir) and Historiography, but he has been described as "an impressively prolific polymath. He wrote on such subjects as world history, poetry, lexicography, grammar, ethics, mathematics, and medicine." His most influential and best known works are his Qur'anic commentary, known in Arabic as Tafsir al-Tabari, and his historical chronicle History of the Prophets and Kings (Tarikh al-Rusul wa al-Muluk), often referred to Tarikh al-Tabari.
