The present work provides a new edition and substantial German commentary of the important theological Arabic work Al-Tamh¿d f¿ bay¿n al-taü¿d ("Introduction to the explanation of monotheism") by the 5th/11th century scholar Ab¿ Shak¿r al-S¿lim¿. The work and its author belong to the theological school that succeeded Ab¿ Man¿¿r al-M¿tur¿d¿ (died 333/944) and still serve as important markers of Sunn¿ theology into the nineteenth century.
