Islam, which literally means peace, submission, and obedience, is the religion of the whole universe. The universe is orderly, a cosmos whose parts are linked together and work together for the same purpose
and goal. This book seeks to present Islam's true face and make it known in a summarized form with most of its aspects: Islam's essentials of faith, principles and ways of worshipping God, morality, and rules ordering human life and relations between people.
