EraIslamic Golden Age

Muhammad ibn Ibrahim ibn Habib ibn Samra ibn Jundab[1] al-Fazari (died 796 or 806) was a Muslim philosopher, mathematician and astronomer.[2][3] 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,[4][5][6][7] other sources state that he was a Persian.[8][9][10]

Al-Fazārī translated many scientific books into Arabic and Persian.[11] He is credited to have built the first astrolabe in the Islamic world.[9]

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.,[12] or the Sindhind. This translation was possibly the vehicle by means of which the Hindu numerals were transmitted from India to Islam.[13]
