The problem with the Muslim methodology is that it could be used to prove that any ancient figure was a prophet of God, especially when many ancients made claims which, unlike Muhammads, actually were scientifically accurate.
For instance, Thales of Miletus was able to predict a solar eclipse in 585 B.C. One could use this to argue that he must have been inspired by God. However, Thales also proclaimed that everything is composed of water, an idea that now seems absurd.
Nevertheless, by employing Islams Miracle of Reinterpretation, we can justify just about any scientific theory in history. For instance, if I were to use Muslim tactics in defending Thales position that everything is made of water, I could make the following argument:
The Prophet Thales claimed that everything is made of water. Thats obviously not true, but Thales was a prophet, so he couldnt have been wrong. So what could he have meant? Well, consider the composition of water. It is made of hydrogen and oxygen. Most of the mass in the universe is in the form of hydrogen, and all living things use oxygen in some way. Thus, we have in Thales statement a full description of the universe—the non-living, predominantly hydrogen part, and the living, oxygen-using part!
But how could Thales have known these things unless God revealed them to him?
Truly this man must be a prophet!
Lo, Prophet Thales, PBUH
Give Thales some credit! He was referring to protons, neutrons and electrons.... everything in the universe is made of these and water has them!! Yay!
