Surah Al-Anbiya, ayah 30

21:30

أَوَلَمۡ يَرَ ٱلَّذِينَ كَفَرُوٓاْ أَنَّ ٱلسَّمَٰوَٰتِ وَٱلۡأَرۡضَ كَانَتَا رَتۡقٗا فَفَتَقۡنَٰهُمَاۖ وَجَعَلۡنَا مِنَ ٱلۡمَآءِ كُلَّ شَيۡءٍ حَيٍّۚ أَفَلَا يُؤۡمِنُونَ ٣٠

Awalam yaral-ladhīna kafarū annas-samāwāti wal-arda kānatā ratqan fafataqnāhumā waja'alnā minal-mā'i kulla shay'in hayyin afalā yu'minūn

Have those who disbelieved not considered that the heavens and the earth were a joined entity, and then We separated them and made from water every living thing? Then will they not believe?
