Ibn Abdun al-Ishbili

His one securely attributed work is the Risala fi'l-qada' wa'l-hisba (Treatise on the Judiciary and Market Inspection), among the earliest surviving manuals of hisba - the regulation of markets and public morals - in al-Andalus. Levi-Provencal edited it in 1955 in his collection of three Andalusi hisba treatises, and a Dar Ibn Hazm edition appeared in 2009. The treatise portrays Almoravid Seville, including its rules for the protected Jewish and Christian communities, which Alejandro Garcia-Sanjuan analysed in a 2008 study ¹².

Ibn Abdun is often styled a qadi, but Garcia-Sanjuan reports Pedro Chalmeta's argument that he may never have held the office - that he was merely a candidate for the qadiship. This record therefore describes him as the jurist who wrote on the judiciary and hisba, without asserting that he served as a judge ².

He must not be confused with Abd al-Majid ibn Abdun, the Badajoz court poet whose Abduniyya qasida laments the fall of the Banu al-Aftas: a different man, with a different full name, city and profession, who shares only the Ibn Abdun name. A third namesake, Muhammad ibn Abdun al-Jabali, was a physician and mathematician. This record covers the Sevillian jurist and hisba author alone ³².
