Muḥammad ibn Ibrāhīm al-Fazārī
Muhammad ibn Ibrahim ibn Habib ibn Samra ibn Jundab al-Fazari was a Muslim philosopher, mathematician and astronomer. 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, other sources state that he was a Persian. Al-Fazārī translated many scientific books into Arabic and Persian. He is credited to have built the first astrolabe in the Islamic world. Along with Yaʿqūb ibn Ṭāriq and his father he helped translate the Indian astronomical text by Brahmagupta, the Brāhmasphuṭasiddhānta, into Arabic as Az-Zīj ‛alā Sinī al-‛Arab., or the Sindhind. This translation was possibly the vehicle by means of which the Hindu numerals were transmitted from India to Islam.
