Is the earth seven, and why is it singled out in the Qur'an?

Question:
The questioner: In many verses, Allah the Exalted begins by mentioning the heavens, then the earth. In Surat Fussilat, Allah mentioned the creation of the earth, then the creation of the heavens. So which was created first, the heavens or the earth?

Answer:
You read Surat Fussilat, and it details that He created the earth in two days and determined its sustenance in two days, then He rose to the heavens. The creation of the earth preceded the creation of the heavens. Yes. As for His saying, the Exalted: , the intended meaning is the spreading out (dahu), which is not the creation. There is a difference between the spreading out and the creation. The spreading out is when He brought out from it its water and its pasture. This is the claim. Yes.
