Narrated Abdullah ibn Mas'ud said (may Allah be well pleased with him):
"Allah’s Messenger said (Allah bless him and give him peace): “I am well aware of the last person to emerge from the Hellfire. After crawling out, he will be told: ‘Go and enter the Garden of Paradise!’ He will therefore enter the Garden of Paradise, but he will find that the people have occupied the abodes, so he will return and say: ‘O my Lord, the people have occupied the abodes!’ He will therefore be asked: ‘Do you remember the time you were in?’ He will say: ‘Yes,’ so he will be told: ‘Make a wish!’ He will make a wish, whereupon he will be told: ‘You have what you wished for, and this world ten times over!’ He will then say: ‘Are you, the Sovereign, mocking me?”’ He said: “I saw Allah’s Messenger (Allah bless him and give him peace) grin so broadly that his molar teeth showed!”
Narrated Abu Dharr said (may Allah be well pleased with him):
“Allah’s Messenger said (Allah bless him and give him peace): "I surely know the first man who will enter the Garden of Paradise, and the last man who will emerge from the Fire of Hell. 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 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!”
