Kitab al-Tawhid
Kitab al-Tawhid (), is the main Sunni theological book, and the primary source of the Maturidi school of thought; written by the Hanafi scholar Abu Mansur al-Maturidi (d. 333/944). Kitab al-Tawhid is monumental work which very nicely expounded the tenets and beliefs of the Ahl al-Sunna wa al-Jama'a and countered the stands of the opponents, such as Karramites, Mu'tazilites, Qadariyya, Majus, Sophists, Dualisms, and Christians. This work is providing a detailed and holistic approach to Islamic theology, whilst also being its earliest extant comprehensive source. Al-Maturidi presents the epistemological foundations of his  teaching and provides detailed arguments in defence of Monotheism, including his cosmological doctrines - such as proofs for the creation and ontology of the Universe. He also focuses on God, His existence and attributes, analyzing issues related to anthropomorphism and rationalism amongst many others. Editions.
