English translation
461. Anas bin Mālik narrated that the Messenger of Allāh ﷺ said: "The rewards of my nation were shown to me, (so much so that I) even (saw the reward of) a man who removes a small speck of filth from the Masjid. And the sins of my nation were shown to me, and I did not see any sin greater than a Sūrah or Verse which a person was given (had memorized) and then forgot." (Da'if)
