There are some verses in the Qur’an which indicate that the earth is round or spherical; here are a few:

1- We read in surah 79 verse 30: “He shaped the earth as an egg after that and brought out its waters and plains.” The word used is dahaha comes from the egg of the ostrich. The science today confirms this: “The Earth is slightly flattened at the poles.  Its equatorial diameter is 45 km (28 miles) longer than its polar diameter. But wait, that’s not all. As well as being generally ovoid, the Earth also has a vertical pear-shaped asymmetry, the north pole being 48 m (148 ft)  further from the equatorial plane than the south pole.”  The “pointy end of the egg “, so to speak, is at about 37° west longitude (400 km off the eastern tip of Brazil) where the equator’s longer axis is 159 m (522 ft) greater than its short axis. The “fat” end is just north of east Papua New Guinea.

2- And in Surah 39 verse 5, “He coils the night upon the day and coils the day upon the night.” As Yahiya Emerick comments in his The Meaning of the Holy Qur’an in Today’s English, ‘this verse is saying that night and day coil or wind around the earth in a circular fashion – like going around a ball – hence the earth is round!”

3- Finally, in Surah 55 verse 17 we read, “He is the Lord of two Easts and Lord of the two Wests.” Once again, let me cite the following note by Yahiya Emerick: “Since the earth rotates on its axis and orbits around the sun, there are two extreme points at which the sun will rise from east and two more extreme points in which it will set to the west during the course of the year, so there are ‘two Easts’ and ‘two Wests. These are called equinoxes.”

Almighty Allah knows best.
