Islam means peace. It is a monotheistic religion based upon the Holy
Qur'an, which adherents believe was sent by Allah through Prophet
Muhammad. Islam is the second-largest religion in the world. The
majority of Muslims are not Arabs (only 20 percent of Muslims originate
from Arab countries). Islam is the second largest religion in the world.
Islam is growing faster numerically than any of the other major world
religions. Muslims believe that God revealed his direct word for
humanity to Muhammad (c. 570–632) through the angel Gabriel and earlier
prophets, including Adam, Noah, Abraham, Moses, and Jesus.
