In 996, he succeeded his first cousin Ibn Abī Zayd as leader (shaykh) of the school in al-Qayrawān (Kairouan).
[1] Al-Qābiṣī's father was born in the village of al-Maʿāfiriyyīn near Qabis (Gabès) and his mother was from al-Qayrawān.
[1] In Africa al-Qābiṣī was taught by Abu ʾl-ʿAbbās al-Ibyānī, a Shāfiʿī scholar from Tunis; Darrās al-Fāsī, an Ashʿarī; and Ibn Masrūr al-Dabbāgh.
He helped spread the Ṣaḥīḥ of al-Bukhārī, a collection of ḥadīths, in northern Africa and wrote for it a riwāya, an account of its transmission.
His other works include a collection of ḥadīths of the Muwaṭṭaʾ, popular in al-Andalus; a treatise on the conduct of schoolmasters, inspired by the writings of Saḥnūn; an incomplete collection of traditions of fiḳh; and numerous letters on everything from Qurʾānic exegesis, the architecture of ribāṭs, the rituals of the ḥajj, the theology of al-Ashʿarī and refuting the Bakrites (i.e., the Khārijites).
