Islam, or Islamism , is the same thing as Muslimism or Mohammedanism, because Mussulmen means Muslims ; it was M. d'Herbelot [1] who introduced these words into our language, and they deserved to be adopted. Islam comes from the verb salama , to resign oneself to the will of God, and to what Mohammed revealed on his behalf, the contents of which are found in the book named the Qur'an, which is to say, the book par excellence. This book, which is chock-full of contradictions, absurdities, and anachronisms, contains almost all of the precepts of Islamism , or of the Muslim religion. We call it alcoran . See Qur'an and Mohammedanism.
