Mountains have always been a symbol of strength and stability, towering over landscapes and enduring the test of time. However, what lies beneath these colossal structures is even more fascinating. Scientists have discovered that mountains are not just massive rock formations above ground—they extend deep into the Earth’s crust, acting like stabilizing pegs for the planet. This fact was already described in the Qur’an over 1400 years ago.
Quran 78:7-8وَٱلْجِبَالَ أَوْتَادًۭا وَخَلَقْنَٰكُمْ أَزْوَٰجًۭا And the mountains as stakes? And We created you in pairs
In these verses, Allah describes the Earth as having been spread out, with mountains placed as pegs. Modern geology confirms that mountains have deep roots, often extending far below the Earth's surface. This discovery aligns with the way mountains are formed—when tectonic plates collide, their impact forces parts of the crust downward, creating deep foundations that anchor the surface.
Mountains play a crucial role in maintaining Earth's stability. They help regulate the movements of tectonic plates, reduce the impact of erosion, and balance the planet's crust against gravitational forces. Essentially, they function as natural stabilizers, preventing excessive shifts in the Earth's surface.

In the 7th century, the depth and function of mountains were unknown. Yet, the Qur’an explicitly mentions their role in stabilizing the Earth, a fact only confirmed through modern scientific advancements. This serves as yet another example of the remarkable insights found within the Qur’an.
