If anyone extols Allah after every prayer thirty-three times, and praises Allah thirty-three times, and declares His Greatness thirty-three times, ninety-nine times in all, and says to complete a hundred:" There is no god but Allah, having no partner with Him, to Him belongs sovereignty and to Him is praise due, and He is Potent over everything," his sins will be forgiven even If these are as abundant as the foam of the sea.  

عَنْ رَسُولِ اللَّهِ ﷺ مَنْ سَبَّحَ اللَّهَ فِي دُبُرِ كُلِّ صَلاَةٍ ثَلاَثًا وَثَلاَثِينَ وَحَمِدَ اللَّهَ ثَلاَثًا وَثَلاَثِينَ وَكَبَّرَ اللَّهَ ثَلاَثًا وَثَلاَثِينَ فَتِلْكَ تِسْعَةٌ وَتِسْعُونَ وَقَالَ تَمَامَ الْمِائَةِ لاَ إِلَهَ إِلاَّ اللَّهُ وَحْدَهُ لاَ شَرِيكَ لَهُ لَهُ الْمُلْكُ وَلَهُ الْحَمْدُ وَهُوَ عَلَى كُلِّ شَىْءٍ قَدِيرٌ غُفِرَتْ خَطَايَاهُ وَإِنْ كَانَتْ مِثْلَ زَبَدِ الْبَحْرِ  

Yahya related to me from Malik from Abu Ubayd, the mawla of Sulayman ibn Abd al-Malik, from Ata ibn Yazid al-Laythi that Abu Hurayra said, "Whoever says 'Glory be to Allah' (Subhana'llah) thirty- three times and 'Allah is Greater' (Allahu akbar) thirty-three times and 'Praise be to Allah' (al-hamdu lillah) thirty-three times, and seals the hundred with 'There is no god but Allah, alone without any partner. The Kingdom and praise belong to Him and He has power over everything' (La ilaha illa'llah, wahdahu la sharika lah, lahu'l mulku wa lahu'l hamd, wa huwa ala kulli shay'in qadir) after every prayer will have his wrong actions forgiven him even if they are abundant as the foam on the sea."  

أَنَّهُ قَالَ مَنْ سَبَّحَ دُبُرَ كُلِّ صَلاَةٍ ثَلاَثًا وَثَلاَثِينَ وَكَبَّرَ ثَلاَثًا وَثَلاَثِينَ وَحَمِدَ ثَلاَثًا وَثَلاَثِينَ وَخَتَمَ الْمِائَةَ بِلاَ إِلَهَ إِلاَّ اللَّهُ وَحْدَهُ لاَ شَرِيكَ لَهُ لَهُ الْمُلْكُ وَلَهُ الْحَمْدُ وَهُوَ عَلَى كُلِّ شَىْءٍ قَدِيرٌ غُفِرَتْ ذُنُوبُهُ وَلَوْ كَانَتْ مِثْلَ زَبَدِ الْبَحْرِ  

If anyone extols Allah after every prayer thirty-three times, and praises Allah thirty-three times, and declares His Greatness thirty-three times, ninety-nine times in all, and says to complete a hundred:" There is no god but Allah, having no partner with Him, to Him belongs sovereignty and to Him is praise due, and He is Potent over everything," his sins will be forgiven even If these are as abundant as the foam of the sea. (Using translation from Muslim 597a)  

قَالَ رَسُولُ اللهِ ﷺ مَنْ سَبَّحَ اللهَ فِي دُبُرِ كُلِّ صَلَاةٍ ثَلَاثًا وَثَلَاثِينَ وَحَمِدَ اللهَ ثَلَاثًا وَثَلَاثِينَ وَكَبَّرَ اللهَ ثَلَاثًا وَثَلَاثِينَ فَتِلْكَ تِسْعٌ وَتِسْعُونَ ثُمَّ قَالَ تَمَامُ الْمِائَةِ لَا إِلَهَ إِلَّا اللهُ وَحْدَهُ لَا شَرِيكَ لَهُ لَهُ الْمُلْكُ وَلَهُ الْحَمْدُ وَهُوَ عَلَى كُلِّ شَيْءٍ قَدِيرٌ غُفِرَ لَهُ خَطَايَاهُ وَإِنْ كَانَتْ مِثْلَ زَبَدِ الْبَحْرِ  

[Machine] The Messenger of Allah ﷺ said: "Whoever says SubhanAllah (Glory be to Allah) thirty-three times, Alhamdulillah (All praise is due to Allah) thirty-three times, and Allahu Akbar (Allah is the Greatest) thirty-three times, and then says La ilaha illallah, wahdahu la sharika lahu, lahul-mulku wa lahul-hamdu, wa Huwa 'ala kulli shay'in Qadir (There is no god but Allah, alone without any partner, to Him belongs sovereignty and to Him belongs all praise, and He is capable over all things) after every Salah (prayer), his sins will be forgiven even if they were as abundant as the foam of the sea."  

قَالَ رَسُولُ اللهِ ﷺ مَنْ سَبَّحَ ثَلَاثًا وَثَلَاثِينَ وَكَبَّرَ ثَلَاثًا وَثَلَاثِينَ وَحَمِدَ ثَلَاثًا وَثَلَاثِينَ وَقَالَ لَا إِلَهَ إِلَّا اللهُ وَحْدَهُ لَا شَرِيكَ لَهُ لَهُ الْمُلْكُ وَلَهُ الْحَمْدُ وَهُوَ عَلَى كُلِّ شَيْءٍ قَدِيرٌ خَلْفَ الصَّلَاةِ غُفِرَ لَهُ ذَنْبُهُ وَلَوْ كَانَ أَكْثَرَ مِنْ زَبَدِ الْبَحْرِ  

[Machine] The Messenger of Allah ﷺ said: "Whoever says behind every prayer thirty-three times of takbeer, thirty-three times of tasbeeh, and thirty-three times of tahmeed, and says 'there is no god but Allah alone, without partner, to Him belongs the dominion and to Him belongs all praise, and He is able to do all things,' his sins will be forgiven even if they are as much as the foam of the sea." Narrated by At-Tirmidhi from Abu Salih from Abu Hurairah with a different wording.  

قَالَ رَسُولُ اللهِ ﷺ مَنْ قَالَ خَلْفَ كُلِّ صَلَاةٍ ثَلَاثًا وَثَلَاثِينَ تَكْبِيرَةً وَثَلَاثًا وَثَلَاثِينَ تَسْبِيحَةً وَثَلَاثًا وَثَلَاثِينَ تَحْمِيدَةً وَيَقُولُ لَا إِلَهَ إِلَّا اللهُ وَحْدَهُ لَا شَرِيكَ لَهُ لَهُ الْمُلْكُ وَلَهُ الْحَمْدُ وَهُوَ عَلَى كُلِّ شَيْءٍ قَدِيرٌ غُفِرَتْ لَهُ خَطَايَاهُ وَإنْ كَانَتْ مِثْلَ زَبَدِ الْبَحْرِ رَوَاهُ سُمَيٌّ عَنْ أَبِي صَالِحٍ عَنْ أَبِي هُرَيْرَةَ بِلَفْظٍ آخَرَ  

If anyone extols Allah after every prayer thirty-three times, and praises Allah thirty-three times, and declares His Greatness thirty-three times, ninety-nine times in all, and says to complete a hundred:" There is no god but Allah, having no partner with Him, to Him belongs sovereignty and to Him is praise due, and He is Potent over everything," his sins will be forgiven even If these are as abundant as the foam of the sea. (Using translation from Muslim 597a)   

قَالَ رَسُولُ اللهِ ﷺ مَنْ سَبَّحَ اللهَ فِي دُبُرِ كُلِّ صَلَاةٍ ثَلَاثًا وَثَلَاثِينَ وَكَبَّرَ اللهَ ثَلَاثًا وَثَلَاثِينَ وَحَمِدَ اللهَ ثَلَاثًا وَثَلَاثِينَ فَتِلْكَ تِسْعَةٌ وَتِسْعُونَ ثُمَّ قَالَ تَمَامَ الْمِائَةِ لَا إِلَهَ إِلَّا اللهُ وَحْدَهُ لَا شَرِيكَ لَهُ لَهُ الْمَلِكُ وَلَهُ الْحَمْدُ وَهُوَ عَلَى كُلِّ شَيْءٍ قَدِيرٌ غُفِرَتْ لَهُ خَطَايَاهُ وَإِنْ كَانَتْ مِثْلَ زَبَدِ الْبَحْرِ  

"مَنْ سَبَّحَ الله في دُبُرِ كُلِّ صَلاة ثَلاثًا وَثَلاثِينَ، وَحَمِدَ الله ثَلاثًا وَثَلاثِينَ، وَكَبَّرَ الله ثَلاثًا وَثَلاثينَ، فَتلْكَ تِسْعَةٌ وَتِسْعُونَ، وَقال تَمَام الْمِائَةِ: لا إِلهَ إِلا الله وَحْدَهُ لا شَرِيكَ لَهُ، لَهُ الْمُلكُ وَلَه الْحَمْدُ، وَهُوَ عَلَى كُلِّ شَيْءٍ قَدِيرٌ، غُفِرَتْ خَطَايَاهُ وَإنْ كَانَتْ مِثْلَ زَبَدِ الْبَحْرِ".
