It is narrated from Sayyiduna Abu Musa رضي الله عنه that the Messenger of Allah صلی اللہ علیہ وآلہ وسلم said: O Abdullah bin Qais!

عن سعد بن أبى وقاص رضى الله عنه قال: كنا عند رسول الله صلى الله عليه وسلم فقال: أيعجز أحدكم أن يكسب كل يوم ألف حسنة؟ فسأله سائل من جلسائه: كيف يكسب أحدنا ألف حسنة؟ قال: يسبح مائة تسبيحة فيكتب له ألف حسنة، أو تحط عنه ألف خطيئة
Sayyiduna Saad bin Abi Waqqas (may Allah be pleased with him) narrates that we were present in the presence of the Messenger of Allah (peace be upon him) when he said: "Can any man earn a thousand good deeds every day?" Then a beggar among your companions asked: How will he earn a thousand good deeds? The Prophet (peace be upon him) said: "If he recites سبحان الله one hundred times, then a thousand good deeds will be written for him, and a thousand mistakes will be forgiven."

عن أبى هريرة أن رسول الله صلى الله عليه وسلم قال: من قال لا إله إلا الله وحده لا شريك له، له الملك وله الحمد وهو على كل شيء قدير، فى 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 بأفضل مما جاء به إلا رجل عمل أكثر منه ، من قال: سبحان الله وبحمده، فى يوم مائة مرة، حطت خطاياه، وإن كانت مثل زبد البحر
Narrated by Sayyiduna Abu Hurairah (may Allah be pleased with him) that the Messenger of Allah (peace be upon him) said: "Whoever says these words one hundred times in a day: لا إله إلا الله وحده لا شريك له، له الملك وله الحمد وهو على كل شيء قدير, he will receive the reward equivalent to freeing ten slaves, one hundred good deeds will be written for him, and one hundred bad deeds will be erased. And these words will be a means of protection for him from Satan until the evening of that day. And on the Day of Judgment, no one will bring a deed more virtuous than this except the one who has done it more than him." And the Prophet (peace be upon him) said: "Whoever recites these words one hundred times in a day: سبحان الله وبحمده, his sins will be forgiven even if they are like the foam of the sea."
