The manual, printed in Arabic and called 'Zad al-Mujahed' (roughly, 'Fruits for the work of God's Warriors') was published in Istanbul, with its publishers making no attempt to even try to hide the book's origins. It features the logo of the Istanbul-based Guraba publishing company, contact information, and even an ISBN, inside its front cover.
Speaking to Sputnik Arabic, the Syrian Army soldier who discovered the book said that it was filled with hatred and calls to war against people who don't share jihadists' faith, as well as instructions on what must be done with "enemies and their property."
"The book describes how to properly burn cities captured by jihadi fighters, how to cut down all the trees, destroy all life, how to execute prisoners in the correct manner," the soldier explained.
"The book says that jihadis have a right to marry their captives; the book even mentions the aspect of the possible use of nuclear weapons," he added.
Syrian authorities are extremely sensitive about published materials which could be seen to inspire sectarian conflict. Before it was engulfed in war in 2011, Syria was known as a secular, multicultural and multiethnic nation with a large number of religious minorities. Since then, many of these minorities have been threatened with enslavement or extermination by homegrown and foreign-sponsored radical Islamist terrorists, including Daesh (ISIS), al-Nusra and a collection of affiliated groups.
