After the prayer, thirty-three of each and the hundredth
Sahihلاَ إِلَهَ إِلاَّ اللَّهُ وَحْدَهُ لاَ شَرِيكَ لَهُ لَهُ الْمُلْكُ وَلَهُ الْحَمْدُ وَهُوَ عَلَى كُلِّ شَىْءٍ قَدِيرٌ
Say subḥānAllāh (glory be to Allah) thirty-three times, al-ḥamdu lillāh (praise be to Allah) thirty-three times and Allāhu akbar (Allah is the greatest) thirty-three times, and complete the hundred with: There is no god but Allah alone, without partner; His is the dominion and His the praise, and He has power over all things.
Virtue: His sins are forgiven, even if they are like the foam of the sea.
