Quran

The Qur'an 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 Qur'an is in every
detail the unique and miraculous text which was revealed to Muhammad
fourteen centuries ago.The Qur'an, 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.
