Sayyiduna Abu Hurairah رضي الله عنه narrates from the Noble Prophet صلى الله عليه وسلم that he صلى الله عليه وسلم said: "Whoever recites «‏‏‏‏سُبْحَانَ اللَٰه» ‏‏‏‏ thirty-three times, «‏‏‏‏الحَمْدُ لِلَٰه» ‏‏‏‏ thirty-three times, and «‏‏‏‏اللهُ أَكْبَرُ» ‏‏‏‏ thirty-three times after the prayer, this makes ninety-nine times. Then, to complete the count to one hundred, he recites «‏‏‏‏لَا إِلَهَ إِلَّا اللَٰهُ وَحْدَهُ، لَا شَرِيكَ لَهُ، لَهُ الْمُلْكُ، وَلَهُ الْحَمْدُ، وَهُوَ عَلَى كُلِّ شَيْءٍ قَدِيرٌ» ‏‏‏‏ 'There is no deity worthy of worship except Allah, He is alone, He has no partner, all sovereignty and all praise belong to Him, and He has power over all things.' — his sins will be forgiven even if they are as much as the foam of the sea."
