وَعَنْ سَعْدَ رَضِيَ اللَّهُ عَنْهُ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: دَعْوَةُ ذِي النُّونِ إِذا دَعَا رَبَّهُ وَهُوَ فِي بَطْنِ الْحُوتِ (لَا إِلَهَ إِلَّا أَنْتَ سُبْحَانَكَ إِنِّي كُنْتُ مِنَ الظالمينَ) لَمْ يَدْعُ بِهَا رَجُلٌ مُسْلِمٌ فِي شَيْءٍ إلاَّ استجابَ لَهُ ". رَوَاهُ أَحْمد وَالتِّرْمِذِيّ
Sa‘d (may God be pleased with him) reported that the Messenger of God (peace be upon him) said: ‘The supplication of Dhu al-Nun, when he called upon his Lord inside the whale, was: “There is no deity but You; glory be to You. I have indeed been among the wrongdoers.” No Muslim supplicates with it for anything without God answering him.’ Ahmad and al-Tirmidhi transmitted it. The Arabic source marks it as not studied by al-Albani.
