There is quite bit of hype among Muslims who's says, it is in the Quran that the Universe is expanding. They quote the verse 51:47. A link that quotes this is here.
Sahih International
And the heaven We constructed with strength, and indeed, We are [its] expander.
Sahih International translation says something but other translations say something else:
Pickthall
We have built the heaven with might, and We it is Who make the vast extent (thereof).
Yusuf Ali
With power and skill did We construct the Firmament: for it is We Who create the vastness of pace.
Shakir
And the heaven, We raised it high with power, and most surely We are the makers of things ample.
What is the truth?
