A Qur?an Commentary by Ibn Barrajan of Seville (d. 536/1141) is a critical Arabic text edition of a medieval Muslim Qur?an commentary entitled, Idah al-hikma bi-ahkam al-?ibra (Wisdom Deciphered, the Unseen Discovered). The annotated Arabic text is accompanied by an analytical introduction and an extensive subject index.This Qur?an commentary is Ibn Barrajan's last and most esoteric work, and as such offers the most explicit articulation of his mystical and philosophical doctrines. It synthesizes his teachings, drawn from a wide array of Islamic disciplines, and provides a link between early Sufism and Muslim mysticism in medieval Spain (Andalusia). The Idah moreover is the earliest known work of its kind to make extensive use of Arabic Biblical material as proof texts for Qur?anic doctrines.
