Abu al-Hasan al-Ahwazi
Abu al-Hasan al-Ahvazi was a Persian mathematician and astronomer of the 4th AH/10th CE and 5th AH/11th 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, 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.
