Dr. Mustafa Khattab, the Clear Quran - Surah Al-Anbya, ayah 30

Translation of Surah Al-Anbya, ayah 30 (21:30)

أَوَلَمۡ يَرَ ٱلَّذِينَ كَفَرُوٓاْ أَنَّ ٱلسَّمَٰوَٰتِ وَٱلۡأَرۡضَ كَانَتَا رَتۡقٗا فَفَتَقۡنَٰهُمَاۖ وَجَعَلۡنَا مِنَ ٱلۡمَآءِ كُلَّ شَيۡءٍ حَيٍّۚ أَفَلَا يُؤۡمِنُونَ ٣٠
Do the disbelievers not realize that the heavens and earth were ˹once˺ one mass then We split them apart?1 And We created from water every living thing. Will they not then believe?
