The Islamic State in Syria and Iraq (ISIS) constitutes the most serious threat Islam has ever faced.

To justify its horrible crimes and appeal to Muslims around the world, ISIS has based its ideology on a superficial and literalist approach to the Sacred Texts of Islam – the Holy Qurân and the Prophetic Tradition. ISIS manipulates religion to brainwash angry young Muslims, who have little knowledge of Islamic theology and jurisprudence.

Therefore, the Muslim scholars are obliged to respond with a counternarrative that elucidates the reality of Islam and its commitment to tolerance. There exists a plethora of proofs that demonstrates ISIS' actions do not represent Sunni Islam and its claims are based on clear fallacies.

The author, Shaykh Muhammad Al-Yaqoubi, a renowned scholar and one of the 500 most influential Muslims in the world today, presents in this invaluable book a thorough refutation of ISIS' beliefs and crimes. Providing authentic quotes that destroy the allegations of ISIS, Shaykh Al-Yaqoubi reaches the conclusion that this group does not represent Islam, its declaration of a caliphate is invalid, and fighting it is an obligation upon Muslims.
