The word “anzalna,” translated as “sent down” and used for iron in the verse, could be thought of having a metaphorical meaning to explain that iron has been given to benefit people.But, when we take into consideration the literal meaning of the word, which is, “being physically sent down from the sky, as this word usage had not been employed in the Quran except literally,
like the descending of the rain or revelation, we realize that this verse implies a very significant scientific miracle. Because, modern astronomical findings have disclosed that the iron found in our world has come from giant stars in outer space.
Not only the iron on earth, but also the iron in the entire Solar System, comes from outer space, since the temperature in the Sun is inadequate for the formation of iron.
The sun has a surface temperature of 6,000 degrees Celsius, and a core temperature of approximately 20 million degrees. Iron can only be produced in much larger stars than the Sun,
where 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 accommodate it,
and it eventually explodes in what is called a “nova” or a “supernova.” These explosions make it possible for iron to be given off into space.
