Yaʿqūb ibn Ṭāriq’s Zīj maḥlūl fī al‐Sindhind li‐darajah darajah (Astronomical tables in the Sindhind resolved for each degree) was based on the Sanskrit original of the Zīj al‐Sindhind, translated by 8th-century scholars in Baghdad.

This work is quoted by al-Hāshimī in " Kitāb ʻilal al-zījāt," and by Abraham ibn Ezra, in the foreword of his translation of the commentary "Tawḍīḥ zīj al-Khwārizimī" of Ahmad ibn al- Muthannah.
