Biography
The caliph ordered al-Fazārī and his son to translate the Indian astronomical text, The Sindhind, along with Yaʿqūb ibn Ṭāriq, which was completed in Baghdad about 750, and entitled Az-Zīj ‛alā Sinī al-‛Arab. This translation was possibly the vehicle by means of which the Hindu numeral system (the modern number notation) was transmitted from India to Iran.
At the end of the 8th century, whilst at the court of the Abbasid Caliphate, al-Fazārī mentioned Ghana, "the land of gold."[1]
Works
Al-Fazari composed various astronomical writings ("On the astrolabe", "On the armillary spheres", "on the calendar").
