The Quran refers to extremists in the following words: "And when it is said to them, 'Do not cause corruption on the Earth,' they say, 'We are but reformers,'" (2:11). Today, ISIS, al-Shabab and other insurgent groups claim to be "reforming" Islam when in fact they are only corrupting its sacred teachings. The Quran also goes on to say that corrupt souls cannot recognize the truth because on their eyes is a "veil" and on their hearts is a "seal," (2:07). Truly, the world in modern times has not known such ignorance as being displayed by extremist groups like ISIS or al-Shabab. These are people who have eyes that cannot see, who have hearts that cannot feel. To call them human would be a disgrace to the human race; to call them monsters would be more fitting.
