He is notable for his correspondence with al-Biruni and for proposing that the Earth rotates around its axis in the 10th century.

He dedicated work to 'Adud al-Daula, who was probably his patron, and to the prince of Balkh. He also worked in Shiraz making astronomical observations from 969 to 970.
