Surah Al-Anbya, Verse 30

أَوَلَمۡ يَرَ ٱلَّذِينَ كَفَرُوٓاْ أَنَّ ٱلسَّمَٰوَٰتِ وَٱلۡأَرۡضَ كَانَتَا رَتۡقٗا فَفَتَقۡنَٰهُمَاۖ وَجَعَلۡنَا مِنَ ٱلۡمَآءِ كُلَّ شَيۡءٍ حَيٍّۚ أَفَلَا يُؤۡمِنُونَ٣٠

awalam yara alladhīna kafarū anna l-samāwāti wal-arḍa kānatā ratqan fafataqnāhumā wajaʿalnā mina l-māi kulla shayin ḥayyin afalā yu'minūna

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?
