Jami` at-Tirmidhi 3505

Ibrahim bin Muhammad bin Sa`d narrated from his father, from Sa`d that the Messenger of Allah (ﷺ) said:“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.”
