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 the dominion, to Him belongs all praise, and He has power over everything,' it will be equivalent for him to freeing ten slaves. One hundred good deeds will be recorded for him, one hundred sins will be erased from him, and it will be a protection for him against Satan that day until evening. No one will come with anything better than what he has brought, except someone who has done more than that. And whoever says, 'Glory be to Allah and praise be to Him,' one hundred times in a day, his sins will be wiped away even if they were like the foam of the sea."
حدثنا يحيى بن يحيى قال قرأت على 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 وكتبت له مائة حسنة ومحيت عنه مائة سيئة وكانت له حرزا من الشيطان يومه ذلك حتى يمسي ولم يأت أحد أفضل مما جاء به إلا أحد عمل أكثر من ذلك ومن قال سبحان الله وبحمده في يوم مائة مرة حطت خطاياه ولو كانت مثل زبد البحر
