[Machine] We were sitting with the Prophet ﷺ , and he said, "Shall I not inform you of something that, if a distress or calamity were to befall one of you, he would supplicate with it and it would be relieved?" They said, "Yes, O Messenger of Allah." He said, "It is the supplication of Dhu'l-Nun, 'There is no deity except You; exalted are You. Indeed, I have been of the wrongdoers.'"
كُنَّا جُلُوسًا عِنْدَ النَّبِيِّ ﷺ فَقَالَ «أَلَا أُخْبِرُكُمْ بِشَيْءٍ إِذَا نَزَلَ بِرَجُلٍ مِنْكُمْ كَرِبٌ أَوْ بَلَاءٌ مِنْ بَلَايَا الدُّنْيَا دَعَا بِهِ يُفَرَّجُ عَنْهُ؟» فَقِيلَ لَهُ بَلَى فَقَالَ دُعَاءُ ذِي النُّونِ لَا إِلَهَ إِلَّا أَنْتَ سُبْحَانَكَ إِنِّي كُنْتُ مِنَ الظَّالِمِينَ
