Whoever glorifies Allah (SubhanAllah) thirty-three times after every prayer, praises Allah (Alhamdulillah) thirty-three times and magnifies Allah (Allahu Akbar) thirty-three times, that is ninety-nine, and completes the hundred with "La ilaha illallahu wahdahu la sharika lah, lahul-mulku wa lahul-hamdu wa huwa ala kulli shay'in qadir", his sins will be forgiven even if they are like the foam of the sea.

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
