Al-Anbya 21:30

Awa lam yara allatheenakafaroo anna assamawati wal-ardakanata ratqan fafataqnahuma wajaAAalnamina alma-i kulla shay-in hayyin afalayu/minoon

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?

Did the disbelievers not observe that the heavens and the earth were closed, then We opened them? And We created from water every living thing. Would they still not believe?
