عَنْ سَعْدِ بْنِ أَبِي وَقَّاصٍ رَضِيَ اللَّهُ عَنْهُ عَنِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ قَالَ دَعْوَةُ ذِي النُّونِ إِذْ هُوَ فِي بَطْنِ الْحُوتِ لَا إِلَهَ إِلَّا أَنْتَ سُبْحَانَكَ إِنِّي كُنْتُ مِنَ الظَّالِمِينَ فَإِنَّهُ لَمْ يَدْعُ بِهَا مُسْلِمٌ رَبَّهُ فِي شَيْءٍ قَطُّ إِلَّا اسْتَجَابَ لَهُ
Narrated from Sayyiduna Sa’d bin Abi Waqqas (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: The supplication of the man of the fish, when he was in the belly of the fish, is: {لَا اِلٰہَ … مِنَ الظَّالِمِینَ} (There is no deity worthy of worship except You; You are pure; indeed, I am among the wrongdoers). Whenever any Muslim calls upon his Lord with this supplication for anything, Allah Almighty will answer his call.
