Hadith on Tasbih: Earning a thousand good deeds in a single day

Sa’d ibn Abi Waqqas reported: The Prophet, peace and blessings be upon him, said, “Is one of you unable to earn one thousand good deeds each day? Let him glorify Allah one hundred times. Thus, it will be recorded for him as one thousand good deeds, or one thousand bad deeds will be erased.
