Ibn Rushd al-Jadd (d. 1136 AD) was the grand-father of Averroes (d. 1196 AD) and the author of a number of works on fiqh. Al-bayan wa al-tahsil is probably his most famous work and based on the Mustakhraja min al-asmi'a of Muhammad al-'Utbi al-Qurtubi (d. 868 AD). The Mustakhraja is an anthology of juridical questions compiled by al-'Utbi through sama' (listening) sessions by interpreters of Maliki doctrine. The present volume is an early copy of the work and was probably copied during the lifetime of Averroes or shortly after his death.
