Al-Ibanah an Usul ad-Diyanah

الإبانة عن أصول الديانة

A creedal work written after Abu al-Hasan al-Ash'ari left the Mu'tazili school, in which he affirms the theology of Imam Ahmad and the early scholars. This work is significant for understanding al-Ash'ari's final theological positions and is cited by both Ash'ari theologians and those who advocate the Athari approach.
