The Qur'an or Koran is the primary holy text of the Islamic religion. According to Muslims, the Qur'an was dictated by God to Muhammad in Classical Arabic through the angel Gabriel. The Qur'an is different from the bible in that its followers generally believe it to be inerrant, infallible and unchanged from that which was dictated by god. Consequently, believing every word of the Qur'an to be the literal word of god is almost universal among muslims. The Qur'an is heavily criticized, especially in the West, for its consideration of women as inferior to men, its advocacy of intolerance towards non-Muslims, and its extremely violent system of punishment for crimes (especially victimless "crimes" such as extramarital sex, homosexuality, blasphemy and apostasy), see Problems with Muslim Sharia Law.
