The Messenger of Allah ﷺ said, "Whoever says one hundred times in a day, 'There is no god but Allah alone, with no partner. To Him belongs all dominion and to Him belongs all praise, and He has power over all things,' will receive the reward of freeing ten slaves. One hundred good deeds will be recorded for him, one hundred bad deeds will be erased from his record, and it will be a protection for him from Satan throughout that day until evening. No one will come with anything better than what he has brought, except a man who has done more than that."
حدثنا عبد الله بن مسلمة عن مالك عن سمي عن أبي صالح
أن رسول الله ﷺ قال من قال لا إله إلا الله وحده لا شريك له له الملك وله الحمد وهو على كل شيء قدير في يوم مائة مرة كانت له عدل عشر رقاب وكتب له مائة حسنة ومحيت عنه مائة سيئة وكانت له حرزا من الشيطان يومه ذلك حتى يمسي ولم يأت أحد بأفضل مما جاء إلا رجل عمل أكثر منه
