Al-Anbya 21:30

أَوَلَمْ يَرَ ٱلَّذِينَ كَفَرُوٓا۟ أَنَّ ٱلسَّمَـٰوَٰتِ وَٱلْأَرْضَ كَانَتَا رَتْقًا فَفَتَقْنَـٰهُمَا ۖ وَجَعَلْنَا مِنَ ٱلْمَآءِ كُلَّ شَىْءٍ حَىٍّ ۖ أَفَلَا يُؤْمِنُونَ

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?
