Surely your Lord is Allah Who created the heavens and the earth in six Days, then established Himself on the Throne, conducting every affair. None can intercede except by His permission. That is Allah—your Lord, so worship Him ˹alone˺. Will you not then be mindful?
It is Allah Who has created seven heavens and of the earth the like thereof (i.e. seven). His Command descends between them (heavens and earth), that you may know that Allah has power over all things, and that Allah surrounds (comprehends) all things in (His) Knowledge.
So in verse number 10:3 it seems to imply that Allah created 7 heavens and 1 earth, but in verse number 65:12 it implies that Allah created 7 heavens and 7 earths.
Is that a contradiction, or it just looks like a controdiction but in reality it is not a contradiction but a misunderstanding of the verse(s).
