under Abū Marwān ibn Ḥazbūl (1). Thereafter he applied himself to the sciences of the ancients, with all their benefits and pitfalls, until he became proverbial in that regard.
Al-Abbār (2) said: “Al-Andalus has never produced anyone who equalled him in perfection, knowledge, and virtue. He was humble, gentle-spirited, and it is reported of him that from the moment he attained understanding he missed study on only two nights: the night his father died and the night of his wedding. The pages he blackened with what he authored and annotated came to about ten thousand folios (3). He was drawn to the disciplines of the philosophers and rose to pre-eminence in them. People would consult his opinions in medicine just as readily as they sought his fatwas in jurisprudence, while he possessed an abundant command of Arabic. It is also said that he had memorised the collected poetry of Abū Tammām and of al-Mutanabbī (4).”
Among his writings are: Bidāyat al-Mujtahid on fiqh, al-Kulliyāt on medicine, Mukhtaṣar al-Mustafā on uṣūl, and a work on Arabic (5).
He held the judgeship of Córdoba, and his conduct in office won praise.
Ibn Abī Uṣaybiʿa states in Taʾrīkh al-Ḥukamāʾ (6): “He was peerless in jurisprudence and dialectical debate, excelled in medicine, and there was a bond of friendship between him and Abū Marwān ibn Zuhr.”
It is further said that he dressed plainly yet possessed a resolute spirit. He studied medicine for a period under Abū Jaʿfar ibn Hārūn. When al-Manṣūr, the ruler of the Maghrib, was in Córdoba, he summoned Ibn Rushd, honoured him greatly, but later took offence at him—namely, on account of philosophy.
His other works include a Commentary on Ibn Sīnā’s Urjūzah on medicine, al-Muqaddimāt on fiqh, and the book al-Ḥayawān.
