Where did iron come from | The interior of Earth in Quran

📖Quran 57:25
We have indeed sent Our messengers with clear proofs, and sent down with them the Book and the Balance, so that people may uphold equity. And We sent down iron in which there is strong power, and benefits.

With a radius of almost 3,500 km (2,200 miles), Earth’s core is about the size of the entire planet Mars. About one-third of Earth’s mass is contained in the core, most of which is liquid iron alloyed with nickel and some lighter, cosmically abundant components (e.g., sulfur, oxygen, and, controversially, even hydrogen). Its liquid nature is revealed by the failure of shear-type seismic waves to penetrate the core. A small, central part of the core, however, below a depth of about 5,100 km (3,200 miles), is solid iron.
