The Qur’an was revealed in a time when this was actually NOT the consensus. 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).
[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 يُكَوِّرُ] the day over the night, and enslaved the sun and the moon. ALL MOVE (Kullon Yajree كل يجري) move to a prerecorded destiny. Is He not the Exalted, the Forgiver?
