Ash-Shama'il Al-Muhammadiyah 228 — The Laughing Of Rasoolullah

The man will be brought forth on the Day of Resurrection, and the command will be given: “Show him his minor sins, and let his major sins be hidden from him!” He will therefore be told: “On such-and-such a day, you committed such-and-such and such-and-such sins!”He will acknowledge [his sins] and not disavow them and he will be fearful of those sins that are major offenses, so the command will be given: “In place of every bad deed he committed, grant him a good deed!” He will therefore say: “I am guilty of sins that I do not see here!” Abu Dharr said: “I saw Allah’s Messenger (Allah bless him and give him peace) smile so broadly that his molar teeth showed!”
