[Machine] Narrated by the Prophet ﷺ, he said: "There are supplications that are never answered negatively; when one says 'Glory be to Allah' thirty-three times, 'Praise be to Allah' thirty-three times, and 'Allah is the Greatest' thirty-three times after every obligatory prayer."
عَنِ النَّبِيِّ ﷺ قَالَ مُعَقِّبَاتٌ لَا يَخِيبُ قَائِلُهُنَّ سُبْحَانَ اللهِ ثَلَاثًا وَثَلَاثِينَ وَالْحَمْدُ لِلَّهِ ثَلَاثًا وَثَلَاثِينَ وَاللهُ أَكْبَرُ ثَلَاثًا وَثَلَاثِينَ فِي دُبُرِ كُلِّ صَلَاةٍ مَكْتُوبَةٍ
