Book excerpt: The present work supplements the original volume of A Bibliography of Islamic Criminal Law, the most extensive bibliography on Islamic criminal law ever compiled. Drawing on a multitude of sources online and offline this bibliography covers in its thematic section not only the classical crime categories of ḥudūd, qiṣāṣ and taʿzīr but also a large number of newly emerging and related fields. In a second section, dedicated to countries, eras and institutions Olaf Köndgen comprehensively covers the historical and modern application of Islamic criminal law in all its forms. Unlocking the richness of this sub-field of Islamic law, also with the help of two detailed indices, this innovative reference work is highly relevant for all those researching Islamic law in general and the application of Islamic criminal law over time in particular.
