In his “Is ISIS a faith-based terrorist group?” (Colombia Journalism Review), Christopher Massie argues:
The real problem [of ISIS] is that nobody can precisely calculate the aggregation of factors that have produced the modern phenomenon of Islamic extremism. And so the claims of people who cite religious causes cannot be dismissed any more than the claims of people who cite political ones. Hussain is right to caution that “Western society doesn’t have a great familiarity with Muslim culture,” and Nomani is also right to say that “we should cover Islam like we cover a city council meeting,” bearing in mind “political interests” and “ideological interests.”
David Wood, in contrast, argues that the main inspiration behind ISIS is Islam in the Qu’ran and the Hadiths.
“Jihadists fighting for ISIS (the Islamic State of Iraq and Syria) claim that they are following the commands of Allah and Muhammad. Yet Westernized Muslims, politicians, and the media claim that ISIS is violating the principles of Islam. Who’s right? In the following video, David Wood presents the top ten Quran verses for understanding the beliefs and actions of ISIS.”
