Al-Luma

Al-Luma' fi al-Radd 'ala Ahl al-Zaygh wa al-Bida' (Arabic: اللمع في الرد على أهل الزيغ والبدع, lit. 'The Gleams in Refutation of the People of Deviation and Innovation'), or simply Al-Luma', is a 10th-century classical Ash'ari theological work authored by the founder of the school, Abu al-Hasan al-Ash'ari. It covers key topics in theology, including Existence of God, His attributes such as speech (kalam), will (irada), and vision, as well as predestination, faith, and the issue of the imamate in Islam, using the kalam method. The work became a foundational text for the Ash'ari school, shaping its doctrines and serving as the basis for later commentaries, with al-Baqillani among the first to write a commentary on it.
