Iron is one of the most essential elements for life on Earth, playing a crucial role in everything from the structure of our planet to the very blood running through our veins. While modern science has revealed the significance of iron in Earth’s core and its melting point under extreme conditions, an intriguing correlation exists within the Qur’an—one that seems to anticipate these scientific discoveries centuries before they were known.
In this article, we explore the remarkable alignment between the Qur’an’s chapter structure and the scientific facts about iron, highlighting an astonishing connection that continues to captivate both believers and skeptics alike.
The Remarkable Placement of Iron in the Qur’an
The Qur’an consists of 114 chapters, making the middle chapter the 57th chapter. This chapter is named “Al-Hadid”, which translates to “Iron”. Interestingly, just as iron is positioned in the middle of the Qur’an in Surah 57, the Earth’s core is also composed primarily of an iron alloy.
Scientific Correlation: Earth’s Iron Core
Adding to this fascinating subtlety, the Earth’s inner core, which consists of an iron alloy, is located approximately 5100 kilometers below the surface.

According to the Lawrence Livermore National Laboratory, two scientists have discovered that iron in Earth-core conditions melts at 5100 Kelvins. Notably, Kelvin is the preferred temperature scale for physicists, astronomers, and chemists as it measures temperatures relative to absolute zero, making it more scientifically precise than arbitrary scales like Celsius and Fahrenheit.
Qur’anic Verse and Iron’s Position
The Qur’an’s first and only verse that explicitly mentions iron is in Chapter 57, Verse 25:
Amazingly, this verse is the 5100th verse of the Qur’an, mirroring the depth of iron in the Earth's core.
Conclusion
Reflecting on these numerical and scientific connections, one can see a profound alignment between the Qur'an's structure and modern scientific discoveries. Whether coincidence or divine precision, the positioning of iron in both the Qur’an and the Earth's core remains a captivating subject of contemplation.
