Islam is not a new religion, but the same truth that God revealed through all His prophets to every people. For a fifth of the world's population, Islam is both a religion and a complete way of life. Muslims follow a religion of peace, mercy, and forgiveness, and the majority have nothing to do with the extremely grave events which have come to be associated with their faith.
Muslims believe in One, Unique, Incomparable God; in the Angels created by Him; in the prophets through whom His revelations were brought to mankind; in the Day of Judgement and individual accountability for actions; in God's complete authority over human destiny and in life after death. Muslims believe in a chain of prophets starting with Adam and including Noah, Abraham, Ishmael, Isaac, Jacob, Joseph, Job, Moses, Aaron, David, Solomon, Elias, Jonah, John the Baptist, and Jesus, peace be upon them. But God's final message to man, a reconfirmation of the eternal message and a summing-up of all that has gone before was revealed to the Prophet Muhammad through Gabriel.
The Quran is a record of the exact words revealed by God through the Angel Gabriel to the Prophet Muhammad. It was memorized by Muhammad and then dictated to his Companions, and written down by scribes, who cross-checked it during his lifetime. Not one word of its 114 chapters, Suras, has been changed over the centuries, so that the Quran is in every detail the unique and miraculous text which was revealed to Muhammad fourteen centuries ago.
The Quran, the last revealed Word of God, is the prime source of every Muslim's faith and practice. It deals with all the subjects which concern us as human beings: wisdom, doctrine, worship, and law, but its basic theme is the relationship between God and His creatures. At the same time it provides guidelines for a just society, proper human conduct and an equitable economic system.
