THE MYSTERY OF IRON
"Indeed We have sent Messengers with clear proofs, and sent down with them the Book and the Balance, that mankind may observe justice; And We sent down (Nazala) iron, in which is (material for) mighty power, as well as many benefits for mankind, that Allah may test who it is that will help, unseen, Him and His Messengers, for Allah is full of strength, exalted in might." (The Quran, 57:25.)
It is remarkable that the Holy Quran uses the word Nazala for iron, stating that it was sent down to earth. Geologists now agree that the entire energy of our solar system is not sufficient to produce one atom of iron. Additionally, they state that four times as much energy as that of our solar system would be needed to make one atom of iron on the surface of earth. The geologists thus conclude that iron is an extra-terrestrial material that came to earth from some other planet. The word Nazala to the early commentators of the Holy Quran was one the mysteries of the Holy Quran. Recent advancement of knowledge has changed this mystery of the Holy Quran to a fact of science. Who besides Allah, Glory be to Him, could have such absolute knowledge which excels and encompasses all levels of human knowledge?
