AZEEM KITAB

Allah Almighty says:

[And He it is Who created the night and the day, and the sun and the moon. They float, each in an orbit.] (Al-Anbiyaa' 21: 33)

This glorious verse refers to a scientific fact concerning the system of the universe. Scientific discoveries have proved that we live in a huge universe that depends on revolution. The earth revolves round the sun once a year, the moon revolves around the earth once per lunar month, and the other planets of the solar system also revolve round the sun, each in its own orbit. Besides, most of these planets have moons that revolve around them, each, also, in its wn orbit. Astronomers have discovered more than 60 of these moons so far.
