There is no scientific mistake in the Quran. The Quran is a religious text, not a scientific textbook. It does not aim to provide scientific explanations or theories.
The Quran contains verses that can be interpreted as referring to scientific concepts, but these interpretations are often based on modern scientific understanding, not on the original context of the verses. For example, the Quran mentions that the earth is an egg-shaped sphere, which is consistent with modern scientific knowledge. However, this interpretation was not understood by the people who lived at the time the Quran was revealed. They likely understood it as a metaphor for the earth's shape, not a literal description.
It is important to note that the Quran is not a scientific text and should not be interpreted as such. Its primary purpose is to guide humanity towards faith and righteousness.
