And the heaven We constructed with strength, and indeed, We are [its] expander.
Sahih International translation says something but other translations say something else:
We have built the heaven with might, and We it is Who make the vast extent (thereof).
With power and skill did We construct the Firmament: for it is We Who create the vastness of pace.
And the heaven, We raised it high with power, and most surely We are the makers of things ample.
What is the truth?
