Iron’s atomic number is 26, not 25, thus surat al-Hadid 25 is out by one. The atomic mass of the most common iron isotope is 56, not 57, thus al-hadid is also out by one.
The rest merely states some of iron’s usefulness. However, this is nothing miraculous as other metals are also useful to humans. Secondly, iron is a common element in our solar system, and possibly in other solar systems. There are no humans except on earth to use this iron. Or did Allah also ‘sent down’ iron on the moon for American astronauts to use?
