Muḥammad ibn Ibrāhīm al-Fazārī

Muhammad ibn Ibrahim al-Fazari (died 796 or 806) was a Muslim philosopher, mathematician and astronomer.[1][2] He is not to be confused with his father Ibrāhīm al-Fazārī, also an astronomer and mathematician.

Some sources refer to him as an Arab,[3][4][5][6] other sources state that he was a Persian.[7][8][9]

Al-Fazārī translated many scientific books into Arabic and Persian.[10] He is credited to have built the first astrolabe in the Islamic world.[8]

Along with Yaʿqūb ibn Ṭāriq and his father he helped translate the Indian astronomical text by Brahmagupta (fl. 7th century), the Brāhmasphuṭasiddhānta, into Arabic as Az-Zīj ‛alā Sinī al-‛Arab.,[11] or the Sindhind. This translation was possibly the vehicle by means of which the Hindu numerals were transmitted from India to Islam.[12]
