Whirlwind induced by fire.
A fire whirl, also known as fire tornado or fire twister, is created when a wildfire or firestorm creates its own wind, which can turn into a vortex of fire.
An extreme example of a fire whirl is the 1923 Great Kantō earthquake in Japan, which ignited a large city-sized firestorm and produced a gigantic fire whirl that killed 38,000 people in fifteen minutes in the Hifukusho-Ato region of Tokyo.

The Quran described this phenomenon long before it was discovered:
[Quran 2.266] Would anyone of you like to have a garden of palms and vines, under which rivers flow, with all kinds of fruit in it for him, and old age has stricken him, and he has weak children, then a tornado containing fire burns it? Thus Allah makes clear the signs for you, so that you may reflect.
1400 years ago the only known tornados were those with rain and hail. Fire tornados were not known at that time.
How could an illiterate man who lived 1400 years ago have known about fire whirls?
