Earth
Earth is a sphere. Moslems say that this is what Allah says. The Quran says that when the night and the day overlap, they make a ball (sphere):
[Quran 39.5] [Allah] Created the heavens and the Earth in truth. He overlaps [Yukawer in Arabic] the night over the day and overlaps [Yukawer] the day over the night, and enslaved the sun and the moon. Everything moves to a prerecorded destiny [on the Preserved Tablet]. Is He not the Exalted, the Forgiver?
The Arabic word "Kura" means ball; its verb "Yukawer" means: to make into a ball. The Quran says that the overlapping of the night and the day makes a ball (sphere).
Science says that the rotation of Earth is slowing down, that is, days are getting longer. Moslems say that this is what Allah says. The Quran says that Allah persistently asks more of the day and more of the night, that is, for the day to get longer:
[Quran 7.54] And your Lord, Allah, who created the Heavens and the Earth in six days and then settled on the Throne (as reference). [Allah] Covers the night with the day, asks for it persistently; and the sun and the moon and the stars enslaved by His orders. Is this not His creation and His command? Blessed be Allah the Lord of all the worlds.
If God asks more of the day and more of the night then this means the days are getting longer. Physics wise, this means that the rotation of Earth should be slowing down. However this is what it really turned out to be: The rotation of Earth is slowing down. How could an illiterate man who lived 1400 years ago have known that the rotation of Earth is slowing down?
