And the earth according to Qur'an is likely flat. I can see now why some orthodox scholars like Sheikh Abdul-Aziz Baaz never supported the heliocentric model of the universe.
Below are just a couple verses;
27:61
Is not He (best) Who made the earth a fixed/resting abode(qararan), and placed rivers in the folds thereof, and placed firm hills therein, and hath set a barrier between the two seas? Is there any god beside Allah? Nay, but most of them know not!
36:38
And the sun runneth on unto a resting-place for him. That is the measuring of the Mighty, the Wise.
36:40
It is not for the sun to overtake the moon, nor doth the night outstrip the day. They float each in an orbit.
The Qur'an several times repeats the sun and moon are in motion but never the earth. To me, this seem at first to be implying the monthly revolution of the moon about the earth and revolution of the sun about the center of the milky way Galaxy. I see a different picture now after looking deeper at the above verses and several more.
Since there is no mention of a moving earth, a fixed and immobile earth is implied when we read 27:61. Given the Qur'an never specifies what the sun and moon orbit, it mean it does not oppose the prevailing knowledge of the time - the earth as the center of the lunar and solar orbits.
The sun and moon motion are often mentioned in context of day and night in the Qur'an. In Geocentric universe model, day and night is tied to revolution of the sun and moon about the earth.
Next, not only does the Qur'an speak of sun's motion, it speaks of the sun running to a "place/abode" for it(36:38). It seem the sun's orbit is a semi orbit with a point where the sun eventually come to a stop, at night. This is only conceivable in a geocentric model with a flat and immobile earth.
On a geocentric model, the sun and moon's orbit are concentric circles. This is implied in 36:40. Because, to consider the sun not overtaking the moon, both objects have to move in the same direction and in orbits that are side to side like concentric circles.
