‘Abdullah bin Mas’ud (May Allah be pleased with him) reported:
The Messenger of Allah (ﷺ) said, “I know of the last of the inhabitants of the Hell to be taken out from there and the last one to enter Jannah. He is a man who will come out of the Fire, crawling on all fours.
Allah, the Rubb of glory and honor will say to him: ‘Go and enter Jannah.’ He will go to it and think that it is full up. He will then come back and say: ‘O my Rubb, it is full up.’
Allah will say to him: ‘Go and enter Jannah.’ He will again go to it and think that it is full up. So he will turn back.
Allah will again say: ‘Go and enter Jannah. For you have what is equal to ten times the world.’
He will say: ‘Are You making fun of me while You are the King?” At this I (i.e., the narrator) saw the Messenger of Allah (ﷺ) laugh till his premolars were visible and he said, “Such man will be the last dweller of Jannah in its lowest rank.”
[Al-Bukhari and Muslim].
Allah is all forever merciful.
