The verse Q. 27:88 of the Holy Qur’an says that the mountains are seen as motionless, while they pass as the passing of the clouds. This verse reveals an important scientific discovery that person has not noticed before. The Quran 27:88 verse tells to the people that mountains are not motionless as they see them, but they are moving as the clouds; it’s certainly to encourage them to discover early that the Earth rotates, thus to understand and explore the Universe. Given the current state of knowledge and depending on the chosen reference frame, obviously mountains will appear as if they are stationary or not. In the Terrestrial Reference Frame, the mountains are motionless; but in the Geocentric Reference Frame however, they are not, they are moving. Therefore, departing from this verse, our goal is to elucidate that the Earth’s rotation and the Sun lies motionless phenomena, let us say, the idea of Copernicus, was revealed in the Qur’an more than 1400 years ago; just understand it at the time. To render the Quran 27:88 verse very clear, we will use some laws of the Mechanics and reference frames of coordinates that are more suitable. Calculation shows that the mountains, like the clouds, move at velocities in the order of 1, 10 to 100 m/s. The intervals of their speeds thus overlap. Moreover, the velocity of mountains depends strongly on the latitude angle unlike that of clouds, and what the verse Q. 27:88 says is not to compare velocities of mountains to those of clouds seen above them, but it mainly reveals the fact that the mountains are not in absolute immobility with respect to the Universe frame of reference, this is to push early people to start doing Sciences of astrophysics more than 1400 years ago.
