On the other hand, the Islam is monotheistic religion that believes in existence of only one God or creator (Allah). The Muslims believe that Qur’an was revealed to Mohammed by Allah, who was the final prophet of God. Mohammed was believed to be a 17th century political and religious leader in the Arabic region. They highly respect Mohammed as the re-instator of the original monotheistic faith and spirituality of Abraham, Moses, Jesus and other great prophets. They hold that the Christians and the Jews tampered with the God’s revelations to His prophets by false interpretation or adding new texts.
