As-Salaam alaikum,
The Prophet, Sallallahu alaihi Wasallam, once asked his companions: "Are you unable to earn 1,000 good deeds a day?" Someone said: "How can we earn 1,000 deeds a day"?

The Prophet, alaihis-Salaat Was-Salaam, replied: "Make 100 Tasbih [recital of SUBHANALLAH ] and 1,000 good deeds will be recorded for you or 1,000 sins will be erased." [Muslim, Hadith 2698].
