How Muslims believed earth was spherical long before anybody mentions it.

Irrational ok. I didn't pay attention at first and thought that I've made some factual mistakes in my own post.

They even believed in gravity, check it out. The Quran also mentions gravity in other verses.

I wonder if the concept of Gravitation is even slightly mentioned in Quaran or Bible, let alon analyzed in any way. It seems like a really irrelevant topic for said scruptures.

I'd like to see what suras get pulled out of AtlasS2's butt to prove gravitation in the Quran.
My further reading on early astronomers on the Indian subcontinent (predating Mohammed and the Quran) shows that they not only were aware that the earth was a sphere (sanskrit 'bhUgola') but they were doing spherical geometry based on this fact to map the stars and locate places on earth.
Realizing that the earth was spherical, they made comments regarding gravity being a pull towards earth's center. "Varahamihira(6th Century AD) had said "It is an experience of everyone that on any part of the earth, that the flames of the fire go up and the objects that were thrown up fall down." Varahamihira published when Mo the Hammed was 5. It looks to me that the Arabs stole more directly from India as much or more than they stole from the Greeks. This makes sense as it was ~800 years after Eratosthenes. If you are going to steal from some culture and call it your own, might as well steal from the most recent you have available.
