Islam started from Adam the first man and prophet on earth. Nonbelievers may say wrongly Muhammad who is born at Saudi Arabia is the founder of Islam and it starts from him. It is big mistake owing to their lack correct knowledge. Islam is the second most popular religion in the world with over a thousand million followers. It is more often thought of as a complete way of life rather than a religion. Some thinkers believed it as movement for complete and ultimate social justice.
Islam began from the human being on earth. It is not only for those who lived in Arabia and it was revealed to humanity by more than hundred thousand Prophets in which Muhammad (peace be upon him) is the last one. Those who follow Islam are called Muslims. Muslims believe that there is only one God, called Allah.
Even though Islam is mainly followed in the Middle East, Asia, and the north of Africa its wide acceptability is going high and high day by day every parts of the world especially in Europe and America.
