Islam is the world's 2nd largest religion with nearly 1.8 billion muslim followers of the faith. Islam's origins date to the 7th century during the time of the prophet Muhammad's life. 

Islam originated in the city of Mecca which is located in modern day Saudi Arabia. The followers of Islam are Muslims.  Islam means “submission to the will of God.” Muslims are monotheistic and worship one, all-knowing God, who in Arabic is known as Allah.

Followers of Islam aim to live a life of complete submission to Allah. They believe that nothing can happen without Allah’s permission, but humans have free will. Islam teaches that Allah’s word was revealed to the prophet Muhammad through the angel Gabriel.

Muslims believe several prophets were sent to teach Allah’s law. They respect some of the same prophets as Jews and Christians, including Abraham, Moses, Noah and Jesus. Muslims contend that Muhammad was the final prophet.

Mosques are places where Muslims worship. Some important Islamic holy places include the Kaaba shrine in Mecca, the Al-Aqsa mosque in Jerusalem, and the Prophet Muhammad’s mosque in Medina.

The Quran (or Koran) is the major holy text of Islam. The Hadith is another important book. Muslims also revere some material found in the Judeo-Christian Bible. Followers worship Allah by praying and reciting the Quran. They believe there will be a day of judgment, and life after death.
