Islam is an Abrahamic monotheistic religion based on the Quran, and the teachings of Muhammad. Adherents of Islam are called Muslims, who are estimated to number 1.9 billion worldwide and are the world's second-largest religious population after Christians. . Muslims believe that Islam is the complete and universal version of a primordial faith that was revealed many times through earlier prophets and messengers, including Adam, Noah, Abraham, Moses, and Jesus. Muslims consider the Quran to be the verbatim word of God and the unaltered, final revelation.
