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

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

Al-Fazari translated many scientific books into Arabic and Persian.[10] He is credited to have built the first astrolabe in the Islamic world.[11]

Along with Yaqub ibn Tariq and his father he helped translate the Indian astronomical text by Brahmagupta (fl. 7th century), the Brahmasphutasiddhanta, into Arabic as Az-Zīj ‛alā Sinī al-‛Arab.[12], or the Sindhind. This translation was possibly the vehicle by means of which the Hindu numerals were transmitted from India to Islam. [13]
