Abu al-Hasan al-Ahwazi

Abu al-Hasan al-Ahvazi (Persian: ابوالحسن اهوازی) was a Persian mathematician and astronomer of the 4th AH/10th CE and 5th AH/11th (CE) centuries. His name suggests that he was originally from Ahvaz. Al-Biruni mentioned his name several times in his works, which indicates that his works were important. Ahvazi himself, mentioned Abū Ja'far al-Khāzin in one of his books. Since Al-Khazin died in 360 AH (c. 982 CE), it can be concluded that the final years of Ahvazi's life was contemporaneous to Biruni's childhood. The only surviving work of Ahvazi is a book named Sharh al-maqala al-ashira min kitab uqlidus.
