Unfortunately, many Muslims have the misconception that the Quran contains all knowledge. This is something that is impossible for two reasons. One, the Quran is limited in its format (about 600 pages); and two, the knowledge of Allah is limitless, He is the All-Knowing. Now, as it goes for the scientific knowledge in the Quran, it is undoubtedly true.
Some of it is clear-cut and gives a pretty exact description of phenomena explained in the Quran; yet unexplained at the time. It has only become evident through time in part because of scientific research and progress. Other bits of knowledge leave place for interpretation and seem ambiguous since it is not explained in intricate detail. And parts, might never even be understood in our lifetime altogether.
Now, when treading in the last two situations, one must be careful not to confirm a new theory because a verse in the Quran leans in that sense; it does not render the theory absolute or true. In any case, the Quran encourages one to contemplate, find explanation and meaning of these signs in nature and the Universe in order to better appreciate and thank Allah. It gives us trails to follow to uncover the laws that govern this Universe so we can use them.
And these are the signs and trails that we are going to explore. Just before diving in, there have been many authors that have spoken about this subject in full and in large. People like Gary Miller (The Amazing Quran), Maurice Bucaille (The Qur’an and Modern Science), Laurence Brown (God’ed), and others. The main reason these people do this is to spread the truth. The secondary reason is that Non-Muslims have trouble reading the Quran on their own. They hear about Islam, have ideas about Islam but do not really know about Islam. The main source, i.e. the Quran, normally should be the first place to start.
