It was 1597 when Francis drake's when he sailed around the earth and then he proved that the earth was spherical.so let see What's the Quran said about earth 1400 years ago.Quran:79: 30-31 And the earth, moreover, hath He 'dahaha' He draweth out therefrom its moisture and its pasture I kept the Arabic word dahaha in its original Arabic form because of the different meanings it has... The word dahaha is derived from the Arabic word daha. The following meanings derive from the word daha 1. To extend. 2. To roll. 3. To even out. 4. Causing to become egg-shaped or creating, making or producing eggs. Amazingly all of dahaha's meanings regarding scientifically true! Scientists have proven that the earth have gone through several stages and shapes. All of these meanings perfectly apply to our planet and the stages that it went through. E.g. dahaha = expansion refers to the expansion of the earth after it was at one point all covered with land with shallow and limited bodies of water. The vast bodies of water that we have today (70%), happened after the expansion of the earth. Yusuf Ali's translation 79: 30-31 '30' And the earth, moreover, hath He extended (to a wide expanse) '31' He draweth out therefrom its moisture and its pasture. These confirm the previous scientific discovery. Khalifa has chosen to translate the word dahaha to egg-shaped (Which is also correct). Therefore, we read his translation as 79:30 He made the earth egg-shaped. The noun dahya is also used by North African Arabs in reference to an egg. It doesn't refer a normal egg. It refers to the egg of an ostrich. We know that the world is not completely round like a ball but it's geo-spherical in shape its flat from the poles and if you an*lyze the shape of the egg of an ostrich that two is geo-spherical in shape.
