Luqman - 31:10
He created the heavens without a pillar that you see. And He placed stabilizers on the earth that you may not be shaken, and He spread therein every kind of creature. And We rained down water from the sky, and We caused to grow therein every beautiful variety.
Why did Allah create everything in pairs?
Council/42:11
It is He Who created the heavens and the earth by splitting them. He created mates for you from among yourselves, and He created livestock in pairs. Thus He produces you therein. There is nothing like Him. He is the Hearing, the Seeing.
The Scatterers/51:49
And We have created everything in pairs that you may take admonition.
