Mishkat al-Masabih 966
Ka'b b. ‘Ujra reported God’s Messenger as saying, “There are certain ejaculations the repeaters (or, performers)* of which after every prescribed prayer will never be caused disappointment:
‘Glory be to God’ thirty-three times, ‘Praise be to God’ thirty-three times, and ‘God is most great’ thirty-four times.”

Muslim transmitted it.
وَعَنْ كَعْبِ بْنِ عُجْرَةَ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: 
" مُعَقِّبَاتٌ لَا يَخِيبُ قَائِلُهُنَّ أَوْ فَاعِلُهُنَّ دُبُرَ كُلِّ صَلَاةٍ مَكْتُوبَة: ثَلَاث وَثَلَاثُونَ تَسْبِيحَة ثَلَاث وَثَلَاثُونَ تَحْمِيدَةً وَأَرْبَعٌ وَثَلَاثُونَ تَكْبِيرَةً ". رَوَاهُ مُسْلِمٌ
