There is no human work in existence that contains statements as far beyond the level of knowledge of its time as the Qur’an. Scientific opinions comparable to those in the Qur’an are the result of modern knowledge. In the commentaries to translations of the Qur’an that have appeared in European languages, I have only been able to find scattered and vague references to them. Nor do commentators writing in Arabic provide a complete study of the aspects of the Qur’an that deal with scientific matters. This is why the idea of a comprehensive study of the problem appealed to me.
