“The supplication of Dhun-Nun (Prophet Yunus) when he supplicated, while in the belly of the whale was: ‘There is none worthy of worship except You, Glory to You, Indeed, I have been of the transgressors. (Lā ilāha illā anta subḥānaka innī kuntu minaẓ-ẓālimīn)’ So indeed, no Muslim man supplicates with it for anything, ever, except Allah responds to him.” (Using translation from Tirmidhī 3505)
قَالَ رَسُولُ اللَّهِ ﷺ «دَعْوَةُ ذِي النُّونِ إِذْ دَعَا وَهُوَ فِي بَطْنِ الْحُوتِ لَا إِلَهَ إِلَّا أَنْتَ سُبْحَانَكَ إِنِّي كُنْتُ مِنَ الظَّالِمِينَ إِنَّهُ لَمْ يَدْعُ بِهَا مُسْلِمٌ فِي شَيْءٍ قَطُّ إِلَّا اسْتَجَابَ اللَّهُ لَهُ بِهَا»
