Abu Ishaq Ibrahim ibn Habib ibn Sulaiman ibn Samura ibn Jundab al-Fazari (Arabic / Persian: أبو إسحاق إبراهيم بن حبيب بن سليمان بن سمورة بن جندب الفزاري) (d. 777 CE) was an 8th-century Muslim mathematician and astronomer of Persian [1] background.
He was the mathematician and astronomer at the Abbasid court of the Caliph Harun al-Rashid. He is 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.[2] This translation was possibly the vehicle by means of which the Hindu numerals were transmitted from India to Islam.[3]
