Answer: The Quran occasionally alludes to natural phenomena in a way that reflects divine wisdom, offering subtle glimpses into the mysteries of creation without delving into detailed scientific explanations. The primary purpose of these references is spiritual guidance, not scientific exposition. Insights into these verses often serve as evidence of the Quran's miraculous nature when understood over time. However, it is crucial not to impose transient scientific theories onto Quranic truths, as scientific understanding evolves, while the Quranic message remains eternal. (1)
The Meaning of "Bahr" (Sea)
In Arabic, the term Bahr originally means "vastness," and it is used to describe large bodies of water due to their expansive nature. For instance, the Nile River is referred to as a Bahr in the story of Prophet Moses. (2) Thus, any substantial body of water, whether a sea, a river, or an underground reservoir, can be called Bahr based on the context. (3)
The Interpretation of "Two Seas"
Scholars have interpreted the "two seas" mentioned in Surah Al-Rahman (55:19-22) in various ways:
- Two specific seas.
- Rivers and seas.
- All freshwater and saltwater bodies.
According to Allama Tabatabai in Al-Mizan, the "two seas" refer to two types of water:
- Saltwater, which constitutes the majority of Earth's surface.
- Freshwater, stored underground or flowing as rivers, which eventually returns to seas.
He notes that these two types of water meet without one overpowering the other, maintaining distinct qualities. This equilibrium occurs both on the surface and underground. (4)
Pearls and Coral in Freshwater and Saltwater
Some have questioned whether pearls (Lulu) and coral (Marjan) are exclusive to saltwater. However, both scientific findings and classical references confirm their presence in freshwater as well:
- Pearls in Freshwater:
- Encyclopaedias like Britannica and Americana document the existence of freshwater pearls in rivers across America, Europe, and Asia. (5)
- The Bustan Encyclopaedia states that pearls can form in freshwater environments.
- Coral in Freshwater:
- Coral, a living organism that attaches to underwater surfaces, is commonly associated with saltwater due to its prevalence in oceans. However, it is also found in certain freshwater bodies.
- For example, Lake Baikal in Russia, the largest freshwater lake in the world, contains coral and other aquatic organisms visible through its transparent ice.
The Quran's reference to pearls and coral emerging from "both seas" can thus be understood as a general statement, encompassing the diverse environments where such treasures are found. (6)
Scientific Observations on Mixing Waters
While rivers and seas eventually mix, the Quran highlights the phenomenon of a barrier (Barzakh) that prevents their waters from blending completely. Modern oceanography confirms this with the discovery of haloclines, where freshwater and saltwater maintain distinct layers due to differences in salinity and density. This separation ensures the coexistence of both water types without neutralizing each other's unique properties. (7)
Conclusion
- The term Bahr in Arabic encompasses various large water bodies, including rivers and underground reservoirs, depending on the context.
- The "two seas" in the Quran likely refer to saltwater and freshwater systems, both of which yield pearls and coral, as confirmed by scientific evidence.
- The Quran's references to natural phenomena aim to inspire reflection on divine creation, not provide exhaustive scientific explanations.
Thus, the questions about freshwater, saltwater, pearls and coral are reconcilable within both classical interpretations and modern scientific findings.
