When the average Islamic State (IS) member is asked why he is fighting, he typically responds, “So that Sharia prevails and Islam’s banner stays high.”
Marwan Shehade, an Islamic scholar and expert on jihadist groups, told Al-Monitor, “There’s no doubt the organization is built on three main elements: the Sharia, the military might and media. Their main slogan is derived from Ibn Taymiyyah’s famous saying, ‘The foundation of this religion is a book that guides and a sword that supports.’ By ‘a book’ they mean the Quran and religion.”
