1400 years ago people thought that the sun was static, that is, it didn't eject anything. However today we know that this is false. The sun ejects coronal mass.
Solar FlareA solar flare is a sudden flash of increased brightness on the Sun, usually observed near its surface and in close proximity to a sunspot group. Powerful flares are often, but not always, accompanied by a coronal mass ejection. Even the most powerful flares are barely detectable in the total solar irradiance (the "solar constant").
The sun ejects coronal mass but this is impossible to see in the naked eye. However this was portrayed in the Quran 1400 years before it was discovered. Hell has three suns so any object would have three shadows:
"As if they were yellow camels" camels are known for their humps. It turned out that our sun throws sparks like yellow hump of a camel
How could an illiterate man who lived 1400 years ago have known how a coronal mass ejection looks like?
The Quran (Koran, the book of Islam) contains scientific knowledge that could not have been known 1400 years ago. It ranges from basic arithmetics to the most advanced topics in astrophysics. You are invited to go through those miracles and judge for yourself.
