Book excerpt: As a response to a request, Imam al-Bajuri, in this short treatise outlines, the core beliefs of the traditional, orthodox Sunni doctrine ('Aqida) that every Muslim should be aware of. Designed to be studied preferably with a teacher or read on one's own, this text will equip the student with sufficient knowledge of the bare essentials of his religion to be able to distinguish truth from falsehood, orthodox from unorthodox, Ahl al-Sunna wa al- Jama'a from others.
