"... And We sent down iron which contained her great strength and a wide range of benefits for humans ...." (Al-Hadid, QS 57: 25)
WORD 'We have sent a' special used for iron in the verse, can be interpreted figuratively to explain that iron was created for the benefit of mankind.
Iron is one of the elements is clearly stated in the Qur'an. In Surat al-Hadid, meaning "iron", we were told as follows:
But when we consider the literal meaning of the word, which "is material derived from the sky", we realize that this verse has a very important scientific miracle.
This is because modern astronomical discoveries have revealed that the iron metal found in the earth we come from giant stars in outer space.
Heavy metals in the universe is created and produced in the core of massive stars. However, our solar system does not have a structure suitable for producing iron independently.
Iron can only be created and produced in stars much larger than the sun, the temperature reaches a few hundred million degrees.
When the amount of iron exceeds a certain level in a star, the star can no longer bear it, and eventually explodes in what is called a "nova" or a "supernova".
As a result of this explosion, meteors containing iron are scattered all over the universe, and they move through a vacuum to pull by gravity experienced celestial body.
All this shows that iron metal is not formed in the earth but the shipment of stars that exploded in space via meteors and "sent down to earth", exactly as stated in the verse.
It is clear that this fact can not be scientifically known in the 7th century when the Qur'an was revealed.
The magic and uniqueness of iron not just stop there. Naturally the element iron has four isotopes, namely 54, 56, 57 and 58. The stable there are three, namely 56, 57 and 58. Of the three Isotopes 57 is the only one that has nuclear spin. Uniquely in the order of Surah Al Hadid (Iron) which is the 57th letter.
Indeed the Qur'an is a guide and a very bright light. All-True God Almighty with all his words.
