It is narrated from Sayyiduna Sa’d (may Allah be pleased with him) that once the Prophet (peace and blessings of Allah be upon him) addressed the noble companions (may Allah be pleased with them all) and said:“Is any one of you incapable of earning a thousand good deeds in a day?”The companions (may Allah be pleased with them) said: O Messenger of Allah! Who has the strength to do that? The Prophet (peace and blessings of Allah be upon him) said:“Let him say «سُبْحَانَ اللّٰهِ» one hundred times; a thousand good deeds will be written for him in his record of deeds and a thousand sins will be erased.”
