He should not to be confused with his son Muḥammad ibn Ibrāhīm al-Fazārī, also an astronomer. He composed various astronomical writings ("on the astrolabe", "on the armillary spheres", "on the calendar"). The Caliph ordered him and his son to translate the Indian astronomical text, The Sindhind along with Yaʿqūb ibn Ṭāriq, which was completed in Baghdad about 750 CE, and entitled Az-Zīj ‛alā Sinī al-‛Arab. This translation was possibly the vehicle by means of which the Hindu numerals were transmitted from India to Iran. At the end of the eighth century, while at the court of the Abbasid Caliphate, this Arab geographer mentioned Ghana, "the land of gold."[1] See also
