Abstract The aim of this paper is to attain a philosophical evaluation of the ideas of the French author Maurice Bucaille. Bucaille formulated an influential discourse regarding the divinity of the Qur’an, which he tried to demonstrate through a comparison of some of its verses with what he defined as scientific data. With his works, which encompass a criticism of the Bible and a defense of creationism, Bucaille furthered the idea that Islam is in harmony with natural sciences, and ensured himself long-lasting fame in the Muslim world. Such ideas have found numerous followers and the description of the “scientific miracles” of the Qur’an has turned into a popular genre. Several attempts have been made to criticize Bucaille about specific positions he holds. The thesis I develop here is that, even if Bucaille's work cannot be easily dismissed, a severe methodological shortcoming emerges through the analysis of the logic behind his claims regarding miraculous and supernatural events. Current attempts at defending the harmony between Islam and science should therefore credit Bucaille, but at the same time, be aware of the risk of inheriting his methodological flaws. In the first section, I briefly recall the works of Bucaille and his contribution to the debate on the harmony between Islam and science. In the second section, I reconstruct Bucaille's view of science and his analysis of the sacred scriptures. In the third section, I investigate how Bucaille characterizes the concept of supernatural. In the fourth section, I put forth a general evaluation of his reasoning.
