In 1976 Bucaille published his book, The Bible, The Qur'an and Science which told that the Qur'an contains no statements contradicting established scientific facts. Bucaille gives examples of astronomy, embryology, and multiple other subjects that had major advances in the 20th century. Bucaille told that the Quran is in agreement with scientific facts, while the Bible is not. He states that in Islam, science and religion have always been "twin sisters" (vii). According to Bucaille, there are "monumental errors" of science in the Bible and not a single error in the Quran. Bucaille's belief is that the Quran's descriptions of natural phenomena make it compatible with modern science. He concludes that the Quran is the Word of God. He also tells that some of the most celebrated scientific discoveries in the 20th century, were described in detail and accuracy.
Bucaille tells that the Old Testament has been distorted 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.
