The shape of the earth is mentioned in the Quran 1400 years ago.
The Quran mentions the actual shape of the earth in the following verse:
"And we have made the earth egg shaped." (Quran 79 : 30)
The Arabic word 'Dahaha' means egg shaped. It also means an expanse. 'Dahaha' is derived from 'Duhiya' which specifically refers to the egg of an ostrich, which is geospherical in shape, exactly like the shape of the earth.
How could Muhammad PBUH have possibly known all this 1400 years ago, when scientists have only recently discovered it?
Quran never said that the earth is flat, as some ignorant claim, on the contrary.
Quran says والأرض بعد ذلك دحاها )( Then after that He made the earth like an egg) (Quran : 79 - 30).
Dahwah دحوة means in Arabic an egg. Some people translate this verse wrongly, claiming that it means spreading it like a flat surface. They need to refer to the original word Dahw and Dahwah.
Those who claim that the earth is flat have misunderstood the meanings of Quranic verses,
little knowledge is dangerous to faith.
It is God who has revealed the Book to you in which some verses are clear statements (which accept no interpretation) and these are the fundamental ideas of the Book, while other verses may have several possibilities. Those whose hearts are perverse, follow the unclear statements in pursuit of their own mischievous goals by interpreting them in a way that will suit their own purpose. No one knows its true interpretations except God and those who have a firm grounding in knowledge say, "We believe in it. All its verses are from our Lord." No one can grasp this fact except the people of reason. [Quran 3 : 7]
Allah has spread the earth out as a carpet for you.
[Quran 71 : 19]
Quranic verses were intentionally misinterpreted by some nonsens, they were trying to misinterpret it to say that "spread out as a carpet" means completely flat. But the wise people say that spread out means spread out all around. That the earth was made vast, expansive, and accessible.
