And many issues like this that the Quraan told about, which proves certainly that the Quraan is a book revealed by Allah onto Prophet Muhammad, and cannot be made by human or angel.
In the year 1910, a chemist known as "Madam Cory" she proved that the atom when bisected, forms energy. This had refuted the Theories that were in effect and used for over 2000 years, by the scientists of that field.
From this, the chemists invented the atomic bomb, and proved that after the explosion of the bomb, they observed that the fire at 5000 Fahrenheit is red, and at 12500 Fahrenheit and above, it turns to white, and at one million Fahrenheit the fire turns to black.
Muhammad the Prophet, that is unlettered, the Arabian, said more than 1400 years ago that: "hellfire was fueled for one thousand years to be red, and one thousand years to become white and one thousand years to become black, and now it's dim black". Who would have knew and confirmed that what the Prophet said was true or even had a meaning among the scientists hundreds of years ago?! Till around the year 1910, the scientists discover and observe what Prophet Muhammad told about, and that it was true.
Allah is great.
ALLAHU AKBAR!!!
THAT'S WHY ISLAM IS FASTEST GROWING RELIGION...
