The Qur'an is the holy book of Islam. Muslims believe the Qur'an is the sayings of God.
Islam teaches that God revealed his message to Muhammad through angel Jibraeel who is the same angel which brought God`s message to the previous prophets. The Qur'an teaches Muslims to follow the right path by only doing good to please God. Muslims believe Allah alone decides who goes to Jannah (Heaven), and that doing good in this lifetime will bring them closer to God.
The Qur'an has a total of 114 chapters. In each chapter, there are many verses. Many Muslims try to memorize the entire Qur'an. A Muslim who does this is called a Hafiz or Hafez.
Other important books in Islam are the Sunnah (which tell about Mohammad's life) and the Hadith
Islam (Arabic: الإسلام, Al-Islam) is a religion that believes in one god. All of its teachings and beliefs are written out in the Qur'an (also spelled Quran or Koran). People who follow Islam are called Muslims. They believe that the Qur'an was spoken to Muhammad by the angel Gabriel, and that it is the word of Allah
