Islam (Arabic: الإسلام, Al-Islam) is a religion that believes in one god.
In Islam, [Allah] is the [Arabic language] word for [god] or 'the
deity'. In Islam the [Qur'an] is named The Criterion, the criterion
between right and wrong, good and evil. The Manual for Mankind
All of its teachings and beliefs are written out in the Qur'an. 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. They view Muhammad as a Prophet.
Other beliefs and rules about what Muslims should do come from reports
of what Muhammad taught and did. Muslims believe Muhammad was Allah's
last prophet.
Muslims believe that there were many other prophets before Muhammad, including Adam, Noah, Abraham, Moses and Jesus.
They believe that all these prophets were given messages of oneness of
God by God to their communities at different times in history of
mankind, but Satan the rebel made the past communities to deviate from
the message of oneness and other social codes. Muslims believe that the
content of Qur'an (written in Arabic) is protected by Allah as mentioned
in Quran and is the final message of God for all of mankind until day
of judgement.
With about 1.8 billion followers (24% of the world's population), Islam
is the second-largest religion in the world. Islam is also the
fastest-growing religion in the world.
The word Islam comes from the term "al-silm" which means peace, and the word "istaslama" (استسلاما) means to "surrender" or "submission (to Allah)".
