The full narration
Yahya related to me from Malik from Sumayy, the mawla of Abu Bakr, from Abu Salih as-Samman from Abu Hurayra that the Messenger of Allah, may Allah bless him and grant him peace, said, "Whoever says, 'Glory be to Allah and with His praise' (Subhana'llah wa bi-hamdihi) one hundred times in a day will have his wrong actions taken away from him, even if they are as abundant as the foam on the sea
