The Quran is a record of the exact words revealed by God through the Angel Gabriel to the Prophet Muhammad (peace be upon him). It was memorized by Muhammad (peace be upon him) and then dictated to his companions, and written down by scribes, who crosschecked it during his lifetime. Not one word of its 114 Surahs, has been changed over the centuries, so that the Quran is in every detail the unique and miraculous text which was revealed to Muhammad (peace be upon him) fourteen centuries ago.
