The name al‐Sijzī indicates that he was a native of Sijistān in southeastern Iran and southwestern Afghanistan. This is confirmed, for example, when al‐Sijzī refers in his al‐Mudkhal ilā ˓ilm al‐handasa (Introduction to Geometry) to a planetarium which he had constructed in Sijistān. Al‐Sijzī was already active in 963, when he copied a manuscript of Pappus' Introduction to Mechanics (Book VIII of the Collection), and still active in 998, when he completed a treatise on the proof of the plane transversal theorem.

Al‐Sijzī's father, Abū'l‐ḥusayn Muḥammad ibn Abd al‐Jalīl, was also interested in geometry and astronomy, and al‐Sijzī addressed some of his works to him, e.g., Risālat f  ī Khawāṣṣ al‐qubba az‐zā'ida wa‐l‐mukāfiya(On Parabolic and Hyperbolic Cupolas), completed in 972. Around 969 al‐Sijzī spent some time at the Buwayhid court in Shirāz and assisted in 969/970 at the...
