Despite common belief there really are no half measures. Muslims believe the Koran to be the irrefutable world of Allah and that Mohammed, a man allegedly beyond reproach, is to be emulated. If people who call themselves Muslim don’t believe that they are not Muslim. Muslims, or Islamists, used to be called ‘Mohammedans’ – followers of Mohammed. An Islamist is simply a follower of Islam – although that word has, in recent years, been associated, erroneously, with people who are willing to follow the more unsavoury advice of Mohammed and the Koran to the letter.
