Al-Anbiya' - 21:87

وَذَا النُّونِ إِذ ذَّهَبَ مُغَاضِبًا فَظَنَّ أَن لَّن نَّقْدِرَ عَلَيْهِ فَنَادَى فِي الظُّلُمَاتِ أَن لَّا إِلَهَ إِلَّا أَنتَ سُبْحَانَكَ إِنِّي كُنتُ مِنَ الظَّالِمِينَ
[21:87]
And Yunus, when he went away in wrath, so he thought that We would not straiten him, so he called out among afflictions: There is no god but Thou, glory be to Thee; surely I am of those who make themselves to suffer loss.
And remember Zun-nun, when he departed in wrath: He imagined that We had no power over him! But he cried through the deptHs of darkness, "There is no god but thou: glory to thee: I was indeed wrong!"
And (mention) Dhu'n-Nun, when he went off in anger and deemed that We had no power over him, but he cried out in the darkness, saying: There is no Allah save Thee. Be Thou Glorified! Lo! I have been a wrong-doer.
