In this book Shaykh Nasir al-Fahd presents his argument with detailed evidence from the Qur'an, Sunnah, Ijma', Qiyas, Historical events and from statements of the Salaf. He uses sound logical reasoning while following the methodology of the Imam's of this Ummah to conclude that whomever assist the Americans in it's current crusade war against the muwahideen (people of Tawheed) commits an act of disbelief that takes him out the fold of Islam. May Allah reward the author and free him.
