"The Book of Jihad" (Kitab al-Jihad) is part of the fragmentary "Book of the Disagreement among Muslim Jurists" (Kitab Ikhtilaf al Fuqaha") by Muhammad ibn Jarir al-Tabari (ca. 839 - ca. 923 C.E.), the famous Muslim historian and Qur"anic commentator. It consists of several sections that deal with different issues related to jihad in classical Islam such as the rules of declaring and conducting war against enemy states and the rules of making peace with the enemy. The present annotated translation of the "Book of Jihad" is based on the original manuscript located in Istanbul, Turkey. This work will appeal to scholars of Islamic Studies as well as Religion, History and Political Science.
