The Messenger of Allah ﷺ said, "Is any one of you incapable of earning a thousand good deeds in a day?"Someone asked, "How can anyone manage that?"He replied, "He glorifies Allah a hundred times, and a thousand good deeds are recorded for him and a thousand bad deeds are erased from him."
حدثنا محمد بن جعفر حدثنا شعبة عن أبي عبد الله مولى جهينة قال سمعت مصعب بن سعد يحدث
عن رسول الله ﷺ أنه قال أيعجز أحدكم أن يكسب في اليوم ألف حسنة قال ومن يطيق ذلك قال يسبح مائة تسبيحة فيكتب له ألف حسنة وتمحى عنه ألف سيئة
Its isnad is sahih. Abu Abdullah, the freedman of Juhayna, is Musa bin Abdullah Juhani, and he is also called by the kunya Abu Salama. He is trustworthy, and Yaala bin Ubayd counted him among four men who were leaders and nobles among the people of Kufa.Muslim narrated the hadith 2:331 through Musa Juhani, and Tirmidhi also narrated it, as mentioned in Dhakhair Mawarith 2095, and it will come again at 1563, 1612, 1613.
