Born in Seville, al-Andalus (now Spain), he received an elite education and travelled widely across al-Andalus. Described as a 'libertine' and yet he was appointed secretary to the Almoravid governor of Granada Abū Yūsuf Tāshfīn ibn ‘Alī; a post he abandoned almost immediately to travel to Morocco in the Maghreb where sometime later he was murdered in his Marrakesh hotel, it was rumoured, on the orders of the sultan.
- Qalā'id al-'Iqyān (قلائد العقيان) ‘Collars of Gold’ or 'Necklace of Rubies'; akhbar (traditions) of poets of the Maghreb and al-Andalus, who were his contemporaries with examples of their poems.
- Maṭmaḥ al-anfus wa-masraḥ al-taʼannus fī mulaḥ ahl al-Andalus (مطمح الأنفس ومسرح التأنس في ملح أهل الأندلس) (Kābir, Wāsiṭ, Saghīr – Large, Medium, Small) 'The Aspiration of the Souls and the Theater of Congeniality in the Anecdotes of the People of al-Andalus'; History of the ministers, scribes and poets of al-Andalus.
These two works are written in rhymed prose full of metaphorical expressions and are an excellent source of information about the apogee of Andalusian letters.
