Born in 1920, Dr. Maurice Bucaille grew up in a Christian household and became chief of the surgical clinic at the University of Paris. After having upset the Christians by exposing the inconsistencies and scientific errors in the Bible, he eventually went on to learn classical Arabic determined to demonstrate that the Qur'an was not the word of God and that it also had inconsistencies or errors.
In a twist of fate, Maurice not only discovered that there were no inconsistencies in the Qur'an but he also discovered the various scientific miracles detailed in the Qur'an which were consistent with modern science and could not have been known to man 1400 years ago, many of which have only been discovered in the past century. Dr. Maurice Bucaille then converted to Islam and wrote a book about his research and journey.

Similarly, Keith Leon Moore, who is of Christian background, was a professor emeritus in the division of anatomy, in the faculty of Surgery, at the University of Toronto, Ontario, Canada. Relating to embryology in the Qur'an, Keith Moore has often validated and emphasized "the accuracy of the statements that were recorded in the 7th century AD, before the science of embryology was established." Moore was also associate dean for Basic Medical Sciences in the university's faculty of Medicine and was Chair of Anatomy from 1976 to 1984. He is a founding member of the American Association of Clinical Anatomists (AACA) and was President of the AACA between 1989 and 1991.
