The Qāḍī Abū Bakr Ibn al-ʿArabī was an Ašʿarite theologian, a Maliki jurist and an Andalusian traditionalist of the fifth-sixth / eleventh-twelfth century. His influence in the Muslim West is undeniable: he is one of the most important figures in the history of ašʿarism in al-Andalus, and introduced kalām books that quickly became references of local teaching, such as the Iršād of al-Ǧuwaynī. He also introduced treatises of uṣūl al-fiqh such as the Mustaṣfā and the Manḫūl of al-Ġazālī. Ibn al-ʿArabī is also the most famous disciple of the latter and one of the first to have transmitted his thought to Andalusian scholars, then to the rest of the Muslim West. Through a critical, introduced, translated and commented edition of his sum of legal theory entitled Nukat al-Maḥṣūl fī ʿilm uṣūl, this present work shows how the legal thought of the Qāḍī is articulated between language and theology.
