Ahmed Raza Khan: Mohammed Aqib Qadri:
Indeed We have sent down the Qur'an, and indeed We Ourselves surely are its Guardians. (This is one of the miracles of the Qur'an - no one has been able to change even one letter of its text, despite every effort. It has remained in its original form since the 6th Century (A.D) and will remain so forever. Other Holy Books such as the Torah and the Bible have lost their originality.)
