We also sent down iron, which is very hard and has many benefits for people.
(Al-Hadid 25. Verse)
Iron is one of the elements highlighted in the Qur'an. Hadid means "iron." The word "anzalna", translated as "we sent down" and used for iron in the verse, may be thought to have a metaphorical meaning to explain that iron benefits people. It is used in the Qur'an to indicate a spiritual event such as either a physical event (rain) or revelation. However, when we consider the true meaning of the word as "physically being sent from the sky", we realize that this verse means a very important scientific miracle. Because modern astronomical findings have revealed that iron found in our earth comes from giant stars in space.
Not only is the iron in the world, but also the iron in the entire solar system comes from outer space, because the temperature in the sun is inadequate for iron formation. The sun has a surface temperature of 5700 °C and a core temperature of approximately 15 million °C. Iron can only be produced in stars much larger than the sun, where the temperature reaches several hundred million degrees. When the amount of iron in a star exceeds a certain level, the star can no longer lift it and eventually explode, dubbed "nova" or "supernova.". These explosions make it possible for iron to be exported into space.
All this shows that iron does not form on Earth, but is transported from supernovae and "lowered" as stated in the verse. It is clear that this truth cannot be known in the 7th century when the Qur'an appeared. Astronomy also revealed that other elements were formed outside the world. In the verse, the expression "also" may be referring to this idea. However, given that these discoveries were made at the end of the 20th century, it is quite surprising that the verse specifically mentions iron.
In his book Nature's Destiny, renowned microbiologist Michael Denton emphasizes the importance of iron: there is nothing more important to life than iron among all metals. It is an iron build-up in the center of a star that triggers a supernova explosion and then the disintegration of life's vital atoms across the universe. It was the gravitational pull of iron atoms to the center of the primitive Earth, which produces the heat that causes the first chemical differentiation of the earth, the gases of the early atmosphere and eventually the formation of the hydrosphere. It is molten iron that acts as a gigantic dynamo in the center of the Earth, producing the Earth's magnetic field, which creates the Van Allen Radiation Belt, which protects the Earth's surface from destructive high-energy penetrating cosmic radiation and protects the important ozone layer from cosmic ray destruction.
Without the iron atom, there would be no carbonbased life in the cosmos. The iron carries oxygen from the lungs and is also connected by carbon dioxide to drive it back to the lungs for processing. Iron also plays a role in the production of enzymes that help digest food, convert blood sugar into energy and many other basic functions. Iron is part of the hemoglobby and iron deficiency results in anemic blood. The intriguing and intimate relationship between life and iron, the red color of blood and the death of a distant star shows not only the interest of metals to biology, but also the biocentricity the cosmos.
In addition, there is another hidden truth in the Qur'an that draws attention to the importance of iron: The Surah Hadid, which refers to iron, contains two very interesting mathematical codes. "Al-Hadid" is the 57th surah of the Koran. When the numerological values of their letters are collected, the "abjad" of the word "Al-Hadid" in Arabic is 57. (An Abjad account is an accounting system of eight words written in Islamic letters, with each letter showing a number.) The value of the word "hadid" is 26. And 26 is the atomic number of iron.
Why Quran doesn't have a surah on silver or gold but it has about iron? Even with all this information, some might say it's just a coincidence. If it's just a coincidence, then it's a really great coincidence.
God knows best of all.
