If anyone is a betting man, he knows that most of the time he will lose; it is a question of numbers. Winning every time is improbable and practically impossible. When flipping a coin, you have one chance out of two of getting it right. 50%, not bad; but repeat it four times straight; not too confident, are you?
Let’s transpose that example to the prophet Muhammad; he got every single verifiable (with our limited knowledge to date) phenomenon right. Not only he got them right, but most of them are also explained; not just enunciated or left for interpretation. Let’s say there are about 20 scientific/natural phenomenon (Actually, more have been mentioned and others left out since a multitude of authors have done a better job than me explaining them. Plus, 20 seems like a pretty round number, and we don’t want to sound boastful either) that were elucidated 1400 years ago, by an illiterate Arab that had no aspirations to science whatsoever… When you do the math: ½ at the power 20 is ½ x ½ x½ x ½ x ½ x ½ x ½ x ½ x ½ x ½ x ½ x ½ x½ x ½ x ½ x ½ x ½ x ½ x ½ x ½. That gives you the possibility of 1/1 048 576 of getting it right. That is less than one in a million probability; becoming less and less a betting man…Keep in mind, considering that the questioning is in a yes or no format; true or false to a given question (without formulating the solution and adding all the explanation that comes with it in the Quran and Hadith).
The thing is, it is not because the prophet Muhammad was an expert in astronomy, geology, chemistry, nuclear physics, biology, botany, entomology, oceanology, or even historical science that he got it right all the time. It is because the only thing he got right out of all of this is that he wholeheartedly believed in Allah. All these, verses, signs, scientific phenomenon were not explained or tackled by the prophet Muhammad; they were brought forth by Allah, the All-Knowing.
And with Him are the keys of the unseen; none knows them except Him. And He knows what is on the land and in the sea. Not a leaf falls but that He knows it. And no grain is there within the darknesses of the earth and no moist or dry [thing] but that it is [written] in a clear record.
Surah Al-Anam (6 – 59)
