عَنْ كَعْبِ بْنِ عُجْرَةَ رضي الله عنه عَنْ رَسُولِ اللهِ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ قَالَ: «مُعَقِّبَاتٌ لَا يَخِيبُ قَائِلُهُنَّ -أَوْ فَاعِلُهُنَّ- دُبُرَ كُلِّ صَلَاةٍ مَكْتُوبَةٍ، ثَلَاثٌ وَثَلَاثُونَ تَسْبِيحَةً، وَثَلَاثٌ وَثَلَاثُونَ تَحْمِيدَةً، وَأَرْبَعٌ وَثَلَاثُونَ تَكْبِيرَةً».
Kutoka kwa Ka'b Bin Ujrah Radhi za Allah ziwe juu yake kutoka kwa Mtume rehema na amani za Allah ziwe juu yake alisema: "Adh-kari za baada ya sala ya faradhi hapati hasara msomaji au mfanyaji wake, kusema Sub-haana llahi mara thelathini na tatu (33), Al-hamdulillahi mara thelethini na tatu (33), Allahu Akbaru mara thelathini na nne (34)".
Ka‘b ibn ‘Ujrah (may Allah be pleased with him) reported that the Messenger of Allah (may Allah's peace and blessings be upon him) said: "There are certain things, the sayer of which – or the performer of which – after every prescribed prayer will never be disappointed: Tasbīh (saying 'Subhānallāh') thirty-three times, Tahmīd (saying 'Al-hamdulillāh') thirty-three times, and Takbīr (saying 'Allāhu Akbar') thirty-four times."
Fadhila za kusema Sub-haanallaah, na Alhamdulillaah, na Allaahu Akbar, maneno haya ndio mema yenye kubakia.
