Abū al‐ʿUqūl Muḥammad ibn Aḥmad al‐Ṭabarī (flourished in Yemen during the 14th century) was a leading astronomer in Ta'izz and the first teacher of astronomy at the Muʾayyadiyya Madrasa. He is known for compiling the largest single corpus of tables for astronomical timekeeping in a specific latitude during medieval times, with over 100,000 entries.[1] Another interesting feature of his work was determining the latitude of Ta'izz as 13° 37' (where the actual is 13° 35').[1]


His epithet al-Tabarī suggests that he or his family stemmed from Tabaristan, a region in northern Iran. He lived in Yemen during the time of the Rasulid Sultan al-Ashraf Umar II and was contemporary to another famous astronomer Muḥammad ibn Abī Bakr al‐Fārisī.[1]
