Who covered the most disciplines, Abū Sahl al-Qūhī or Al-Farabi?
Al-Farabi Al-Farabi ( ; Persian: ابو نصر محمد بن محمد فارابي‎ ‎ "Abū Naṣr Muḥammad ibn Muḥammad Al Fārābī ";, known in the West as Alpharabius (c. 872 in Fārāb – between 14 December, 950 and 12 January, 951 in Damascus), was a renowned philosopher and jurist who wrote in the fields of political philosophy, metaphysics, ethics and logic. He was also a scientist, cosmologist, mathematician and music scholar.
Ibn Abi Zar Abū al-Hassan ‘Alī ibn Abī Zar‘ al-Fāsī (Arabic: أبو الحسن علي بن أبي زرع الفاسي‎ ‎ ) (d. between 1310 and 1320) is the commonly presumed original author of the popular and influential medieval history of Morocco known as "Rawd al-Qirtas", said to have been written at the instigation of Marinid Sultan Abu Sa'id Uthman II. His full nasab is sometimes given as "ibn Abd Allah ibn Abi Zar" and sometimes as "ibn Muhammad ibn Ahmad ibn Umar ibn Abi Zar". The uncertainty about his name and authorship of the Rawd is caused by the many variant manuscripts in circulation since the Middle Ages. Very little is known about his life except that he was evidently a scholar at Fes.
