Maurice Bucaille (French pronunciation: [moris bykaj]; 19 July 1920 in Pont-l'Évêque, Calvados – 17 February 1998), son of Maurice and Marie (James) Bucaille, was a French medical doctor, member of the French Society of Egyptology, and an author. Bucaille practiced medicine from 1945–82 and was a specialist in gastroenterology. In 1973, Bucaille was appointed family physician to king Faisal of Saudi Arabia. Another of his patients at the time included members of the family of then President of Egypt, Anwar Sadat.
Bucaille writes that the Old Testament has been distorted (tahrif) because of numerous translations and corrections as it was transmitted orally. He highlights, in his words, "numerous disagreements and repetitions", in the Old Testament and the Gospels. In his analysis, he states that he makes use of many propositions of biblical criticism, such as the documentary hypothesis.
Bucaille urged in his book that since the Bible is not consistent with the modern scientific knowledge, it is not a divine scripture at all. On the contrary, there is not a single verse found in the holy Quran inconsistent to science, so it is fully scientific and purely divine scripture.
"Bucailleism" is a term used for the movement to relate modern science with religion, and especially that of Islam. Since the publishing of The Bible, the Quran and Science, Bucaillists have promoted the idea that the Quran is of divine origin, arguing that it contains scientifically correct facts.
According to The Wall Street Journal, Bucailleism is "in some ways the Muslim counterpart to Christian creationism" although "while creationism rejects much of modern science, Bucailleism embraces it". It described Bucailleism as being "disdained by most mainstream scholars" but said it has fostered pride in Muslim heritage and played an important role in attracting converts.
