Dr Maurice Bucaille explains that the Bible was assembled from varied oral traditions, and presents internal contradictions and scientific errors. Nothing radical here, this view is more or less shared by many Christians, even though they wouldn't accept Dr Bucaille's conclusion that the Bible is religiously flawed. What was new, to me, was Dr Bucaille's claim that the Qur'an not only is free from such problems, but even anticipates modern scientific discoveries. How does Dr Bucaille demonstrate this startling claim? Here are a few examples.
The Qur'an (21:33, i.e. sura 21, verse 33) states that "(God) is the One Who created the night, the day, the sun and the moon. Each is travelling in an orbit with its own motion." Now, this, Dr Bucaille assures us (p. 158-61), means that the moon orbits the earth, and the sun orbits the centre of the Milky Way! Modern science discovered the latter orbit only centuries after it had been stated in the Qur'an!
The Qur'an describes the sequence of night and day, Dr Bucaille explains, without reference to the wrong idea, widespread at the time, that the sun moves about the Earth (p. 163). He quotes (31:29) "Hast thou not seen how God merges night into day and merges day into night;" But Dr Bucaille does not tell us that the verse continues so: "that He subjected the moon and the sun (to His Law), each running its course for the term appointed (...) ?" He does quote that bit, but in a different page (p. 165) after he has changed topic. You might think the "course for the term appointed" might refer to apparent course of the sun between sunrise and sunset, and that of the moon through the night sky, but Dr Bucaille does not even mention those possibilities; the courses are the entire lifetime of the moon and sun, which are estimated to end in a few billion years! Nobody knew this at the time of Mohammed!
The Qur'an contains many verses regarding human reproduction, such as (75:37) "Was man not a small quantity of sperm which has been poured out?" and (23:13) "Then [Allah] placed (man) as a small quantity (of sperm) in a safe lodging firmly established." So we learn from the Qur'an, Dr Bucaille tells us, that the "quantity of liquid needed in the fertilisation process" is "very small", "which is in strict agreement with what we know on this subject today" (p. 201). Unfortunately Dr Bucaille does not clarify exactly how revolutionary this idea was at the time; namely, whether people used to believe that fertilisation required multiple intercourses so that a large quantity of sperm could be accumulated.
All in all, this book is an extraordinary revelation... of the mind of an apologist.
