أَوَلَمْ يَرَ ٱلَّذِينَ كَفَرُوٓا۟ أَنَّ ٱلسَّمَٰوَٰتِ وَٱلْأَرْضَ كَانَتَا رَتْقًۭا فَفَتَقْنَٰهُمَا ۖ وَجَعَلْنَا مِنَ ٱلْمَآءِ كُلَّ شَىْءٍ حَىٍّ ۖ أَفَلَا يُؤْمِنُونَ
Do the disbelievers not see that the heavens and the earth were one mass, and We tore them apart? And We made from water every living thing. Will they not believe?
The Holy Quran · Al-Anbiyaa (The Prophets) · 21:30
وَٱلسَّمَآءَ بَنَيْنَٰهَا بِأَيْي۟دٍۢ وَإِنَّا لَمُوسِعُونَ
We constructed the universe with power, and We are expanding it.
