Islam is the name of the second largest major religion in the world. The Arabic word Islam means peace and submission to God. A follower of Islam is called a Muslim. A Muslim strives to live in peace and harmony with the Creator, oneself, other people and the environment. Thus Islam is not only a religion, but a way of life.
Muslims believe in only One God, the same God that Jews and Christians believe in, but some of the ideas about the nature of God are different.
First, let us clarify that “Allah” is simply the Arabic word for God, just as “Dios” or “Dieu” are the words for God in Spanish and French, respectively. “Allah” is His name, and it is also the word used by Arabic-speaking Christians. So it is wrong to say that Muslims believe in a different god than the Christians and Jews believe in.
The Qur’an is the Book of Allah (God) that was revealed in Arabic to the Prophet Muhammad (peace and blessings be upon him) over a period of twenty-three years. He dictated it to his followers as he received it from the Angel Jibril (Gabriel), and they wrote it down on whatever materials were available. The Prophet and many of his followers memorized it as it was revealed.
