Part of verse 87 of Surah Al-Anbiya, the prayer of Prophet Yunus from inside the whale.
It reads 'There is no god but You, glory be to You, I have surely been among the wrongdoers.' The Prophet (peace be upon him) said that no Muslim ever supplicates with these words for anything without Allah answering him (Sunan at-Tirmidhi). It is a beloved dua for distress and turning back to Allah.
- 21:87
وَذَا ٱلنُّونِ إِذ ذَّهَبَ مُغَٰضِبًۭا فَظَنَّ أَن لَّن نَّقْدِرَ عَلَيْهِ فَنَادَىٰ فِى ٱلظُّلُمَٰتِ أَن لَّآ إِلَٰهَ إِلَّآ أَنتَ سُبْحَٰنَكَ إِنِّى كُنتُ مِنَ ٱلظَّٰلِمِينَ
