When Moslems pray they prostrate to Allah:
They bend down so that their faces become parallel to the ground. Now imagine that they don't bend down but rather the ground curves upward in order to become parallel to their faces. But this is what really happens in stars.
Spacetime curves to become parallel to the star's face. This is because matter tells spacetime how to curve.
"Spacetime tells matter how to move; matter tells spacetime how to curve."
Geons, Black Holes, and Quantum Foam (2000), John Wheeler & Kenneth Ford, p. 235.
But 1400 years ago the Quran said that stars prostrate to Allah.
[Quran 55.6] And the stars and the trees prostrate.
Today we know that stars prostrate because spacetime itself is curved such that it is parallel to the star's face. This is true for anything that has mass.
How could an illiterate man who lived 1400 years ago have known that matter curves spacetime?
