مُعَقِّبَاتٌ لاَ يَخِيبُ قَائِلُهُنَّ - أَوْ فَاعِلُهُنَّ - ثَلاَثٌ وَثَلاَثُونَ تَسْبِيحَةً وَثَلاَثٌ وَثَلاَثُونَ تَحْمِيدَةً وَأَرْبَعٌ وَثَلاَثُونَ تَكْبِيرَةً فِي دُبُرِ كُلِّ صَلاَةٍ "
Ka'b b. 'Ujra reported Allah's Messenger (ﷺ) as saying: There are certain remembrances, the repeaters of which or the performers of which at the end of every prayer will never be caused disappointment:" Glory be to Allah" thirty-three times," Praise be to Allah" thirty-three times, and" Allah is most Great" thirty-four times.
