Mus`ab bin Sa`d narrated from his father, that :the Messenger of Allah (ﷺ) said to those sitting with him: “Is one of you incapable of attaining a thousand good deeds?” So a questioner among those seated with him asked him: “How can one of us earn a thousand good deeds?” He said: “(When) one of you recites a hundred Tasbīḥāt a thousand good deeds are written for him, and a thousand evil deeds are wiped away from him.”
