Quran 21:87 from Surah Al-Anbiyaa on Divine Marvels.
وَذَا ٱلنُّونِ إِذ ذَّهَبَ مُغَٰضِبٗا فَظَنَّ أَن لَّن نَّقۡدِرَ عَلَيۡهِ فَنَادَىٰ فِي ٱلظُّلُمَٰتِ أَن لَّآ إِلَٰهَ إِلَّآ أَنتَ سُبۡحَٰنَكَ إِنِّي كُنتُ مِنَ ٱلظَّٰلِمِينَ
English translation: And Dhun-Nun And Dhun-Nun when he went (while) angry and thought that never We would decree upon him Then he called in the darkness(es) that (There is) no god except You Glory be to You Indeed, [I] I am of the wrongdoers
Transliteration: wadha al-nuni idh dhahaba mughadiban fazanna an lan naqdira alayhi fanada fi al-zulumati an la ilaha illa anta sub'hanaka inni kuntu mina al-zalimina
