The very claim of "scientific miracles" always puzzled me, as a very short thought on that idea must tell any reasonable person that such a claim is plain silly. Nobody ever suggests that their old high school maths book are a source of religious inspiration, so what on earth can be gained by turning the Qur'an, such as it is, into a science book?
The process is always one of retroactive re-reading. Once some scientific idea is known, a passage of the Qur'an that be tentatively related to that is actively searched for, and then re-evaluated as to what it "really" says. Never, not even once ever so slightly, did the Qur'an enable or inform any kind of scientific enquiry, it is always the other way round... scientific discoveries re-define the meaning of the Qur'an.
However there is also a reverse process. For some of the more outlandish claims in the Qur'an, such as the setting place of the sun or the inability of salt and fresh water to mix, people either search for slightly related phenomena and suggest that this is was the text "actually" means (as in case with the salt and fresh water) or they suggest an allegorical reading even when the text is quite clear that is meant to be taken literally, such as with the setting place of the sun.
People making such claims just make themselves look ridiculous.
Also, what is very noticeable, not ALL scientific findings are "anchored" in the Qur'an... in biology, evolution and natural selection feature heavily, as do "family trees" of all animals, including humans. I have not yet come across anyone trying to find these things in the Qur'an yet, have you?
Jesus: "Ask and you will receive." Mohammed: "Take and give me 20%"
The story of the filthy water is a new one to me. It's too late to look it up now, but I'm sure there are old accounts of wells being deliberately polluted or poisoned, perhaps during sieges.
