لَا إِلَٰهَ إِلَّا أَنتَ سُبْحَانَكَ إِنِّي كُنتُ مِنَ الظَّالِمِينَ
La ilaha illa Anta Subhanaka inni kuntu minaz-zalimin
There is no deity except You; exalted are You. Indeed, I have been of the wrongdoers.
This is the du'a of Prophet Yunus (Jonah), peace be upon him, when he was swallowed by the whale and cried out from within the depths of darkness. The Prophet ﷺ said: "No Muslim makes du'a with this supplication regarding any matter except that Allah answers him." It combines tawhid (declaring God's oneness), tasbih (glorification), and confession of wrongdoing.
