Rasulullah (sallallahu ‘alayhi wa sallam) once asked the Sahabah, ‘Are you unable to earn one thousand good deeds a day’? Someone said, ‘How can we earn one thousand good deeds a day’? Nabi (sallallahu ‘alayhi wa sallam) replied, ‘Make one hundred Tasbih [Subhanallah] and one thousand good deeds will be recorded for you or one thousand sins will be erased” [Some versions state, One thousand good deeds will be recorded and one thousand sins erased].... (Sahih Muslim, Hadith: 2698)
