It is narrated from Sayyiduna Abu Huraira, may Allah be pleased with him, that the Messenger of Allah, peace and blessings be upon him, said: "Whoever says «لَا إِلَهَ إِلَّا اللّٰهُ وَحْدَهُ لَا شَرِيكَ لَهُ، لَهُ الْمُلْكُ وَلَهُ الْحَمْدُ وَهُوَ عَلَى كُلِّ شَيْءٍ قَدِيرٌ» one hundred times in a day, it is as if he has freed ten slaves, and one hundred good deeds will be written for him, and one hundred sins will be erased from him, and he will be protected from the evil of Satan for the whole day until evening, and no one will bring a better deed than this except the one who does more than this."
