The ocean covers most of our planet, yet its water is famously undrinkable. In classical Islamic medicine (Tibb-e-Nabawi) and jurisprudence, seawater holds a very unique status. It is a purifier, a preserver of global health, and a subject of fascinating ancient survival science.

Let’s explore the Prophetic rulings on seawater, the divine wisdom behind its intense saltiness, and how ancient scholars figured out how to desalinate it centuries ago!

The Prophetic Ruling on Seawater

Because seawater is so heavily saturated with salt and tastes so different from fresh river water, early Muslims wondered if it was pure enough to use for Wudu (ritual ablution).

When asked about the seawater, the Prophet Muhammad (ﷺ) gave a profound and foundational ruling:

“Its water is a purifier, and its dead (animals) are Halal (permissible).” (Sunan Abi Dawud)

This means that not only can seawater be used for purification, but any creature that naturally lives and dies in the sea (fish, etc.) is permissible to eat without requiring ritual slaughter.

The Divine Wisdom: Why is the Ocean Salty?

If water is the source of life, why did Allah Almighty make the largest bodies of water on earth extremely salty, brackish, and bitter? Classical scholars pondered this and arrived at a brilliant ecological conclusion.

The sea is a massive, stagnant basin where millions of living creatures reside and eventually die. Unlike land animals, sea creatures are not buried in the earth. If the ocean were made of sweet, fresh water, the continuous accumulation of dead bodies would cause the water to putrefy. This massive rotting would release toxic odors, corrupt the world’s air, and ultimately destroy the global ecosystem.

Therefore, Allah made the ocean a massive “repository of salt.” Salt is the ultimate natural preservative. No matter how much biological matter dies in the ocean, the intense saltiness acts as a global disinfectant, keeping the water pure and the world’s air clean until the end of time.

Medical Effects: Bathing vs. Drinking

In humoral medicine, seawater has very specific effects on the human body:

• Bathing (External): Bathing in seawater is highly praised in classical texts. Because of its mineral density and salt content, it actively repels and cures various skin diseases.
• Drinking (Internal): Drinking raw seawater is extremely harmful. Classical physicians noted that it causes severe diarrhea, rapid weight loss (thinning of the body), intense internal itching in the belly, and actually worsens dehydration and thirst.

Ancient Survival Hacks: Classical Desalination

What if you are stranded on a coastline or out at sea with no fresh water? Long before modern desalination plants, classical Islamic scholars documented brilliant, low-tech methods to extract sweet water from the sea:

Method 1: The Wool Condenser (Distillation)

Boil seawater in a large pot. Place a bundle of fresh, carded wool securely over the mouth of the pot. As the water boils, pure, salt-free steam rises and is absorbed by the wool, while the heavy salt and impurities are left behind in the pot. Once the wool is saturated with moisture, simply squeeze the pure, distilled water into a separate vessel!

Method 2: The Multi-Pit Filtration System

Dig a wide pit on the sandy shore near the sea, allowing seawater to seep into it. Right next to it, dig a second pit so water from the first pit seeps through the sand wall into the second. Then, dig a third pit. By forcing the water to continuously seep through thick walls of dense coastal sand, the earth naturally filters out the salt. By the third or fourth pit, the water that accumulates will be sweet and drinkable!

Bonus: Purifying Muddy Water

Classical texts also provided “hacks” for dealing with muddy freshwater. If your water is cloudy with sediment, ancient physicians recommended dropping in apricot pits, a piece of teak wood (Sagwan), a piece of burning coal, Armenian clay, or alum (Phitkari). These act as natural coagulants, causing the mud to instantly settle to the bottom and leaving the top water clear!
