The document discusses whether the Earth spins or rotates. It provides evidence from the Quran and science to prove that the Earth rotates. Verses from the Quran reference the sun and moon having an appointed course and the mountains being stabilizers. Scientifically, if the Earth did not rotate planes, helicopters, and slow flying birds would not be able to reach their destinations due to the Earth's speed of rotation being much faster than their flight speeds. Any additional questions about the Earth rotating can be directed to the provided email address.
