“Indeed, good deeds do away with misdeeds.”

And establish prayer at the two ends of the day and at the approach of the night. Indeed, good deeds do away with misdeeds. That is a reminder for those who remember.

The line sits inside a command to pray at the two ends of the day and in the hours of the night — and Ibn Kathir notes it was revealed before the five daily prayers were made obligatory. His commentary glosses the promise with the Prophet’s (peace be upon him) own image, recorded in the Sahih: if a river ran past your door and you washed in it five times a day, would any dirt be left on you? That, he said, is the likeness of the five prayers.
