Discovery of Hydrogen

Imam Muḥammad al‑Bāqir’s (AS) statement about hydrogen in water and the possibility of turning water into fire is one of the most striking examples of early scientific insight in Islamic history. When expressed clearly and placed beside what modern chemistry now knows, the depth of his knowledge becomes unmistakable.  He taught that water contains a component that is highly inflammable, and that through scientific methods, water can be turned into fire. This is an astonishingly accurate description of hydrogen, the first element of the periodic table and one of the most flammable substances known to science.



1. Water is composed of hydrogen and oxygen

Modern chemistry shows that water (H₂O) is made of:

  • Hydrogen (H₂) — a highly flammable gas
  • Oxygen (O₂) — the gas that supports combustion


This was discovered in the late 18th century by Lavoisier and Cavendish—over 1,000 years after Imam al‑Bāqir (AS).


2. Hydrogen is extremely flammable


  • Ignites easily
  • Burns with a nearly invisible flame
  • Is used today as a rocket fuel
  • Produces water when burned


The Imam’s description of hydrogen as a “highly inflammable gas” is scientifically precise.


3. Water can be turned into fire

This sounds paradoxical—until you consider electrolysis. Through electrolysis:

  • Water is split into hydrogen and oxygen
  • Hydrogen can then be ignited
  • Oxygen intensifies the flame


Thus, water can indeed be used to create fire, exactly as the Imam said.

This process was not discovered until 1800, when Nicholson and Carlisle first performed electrolysis.


At the time of Imam al‑Bāqir (AS):

  • The structure of matter was unknown
  • No one knew water was a compound
  • Hydrogen had not been discovered
  • Electrolysis was centuries away
  • Chemistry was still based on Aristotle’s Four‑Element theory
  • No scientific instruments existed to separate gases


Yet the Imam described:

  • The composition of water
  • The presence of a flammable component
  • The ability to extract it
  • The possibility of producing fire from water
  • This is not metaphorical language—it is chemically accurate.

 

How does this fit the broader pattern of the Imams’ Scientific Knowledge?


Imam al‑Ṣādiq (AS) describing

  • Microorganisms
  • Explaining blood circulation
  • Describing atomic motion
  • Predicting plate tectonics
  • Explaining solar fusion
  • Rejecting geocentrism
  • Describing oxygen in air
  • Explaining universal motion
  • Describing the origin of the universe from a tiny particle


Each example shows knowledge far beyond the scientific horizon of their time.

Within the Shia understanding, this is part of ʿilm ladunnī—knowledge granted directly by Allah (SWT) to His chosen Representatives.
