Orbital Motion For centuries it was believed that Earth is fixed and the sun, moon and planets revolve around it. However 1400 years ago the Quran said that not only the sun and moon but even Earth moves in a designated path: [Quran 39.5] [Allah] Created the heavens and the Earth in truth. He overlaps the night over the day and overlaps the day over the night, and enslaved the sun and the moon, ALL MOVE (Kullon Yajree )كل يجريto a prerecorded destiny. Is He not the Exalted, the Forgiver? Here the Quran is referring to ALL MOVING: not only the sun and moon but also Earth. In Arabic grammar there is difference between the singular (one), binary (two) and plural (three or more). The reference to binary is "Kulahuma Yajreean "كلهما يجريانhowever the Quran said "Kullon yajree "كل يجريreferring to the plural (three or more). Since the sun and moon are just two but the Quran refers to three or more then according to the Quran all the three move: sun, moon and Earth. Moslems ask how could an illiterate man who lived 1400 years ago have known that Earth moves?
