Chapter: The Talk of the Lord عزّ وجلّ to the Prophets and others on the Day of Resurrection
Narrated `Abdullah:
Allah's Messenger (ﷺ) said, "The person who will be the last one to enter Paradise and the last to come out of Hell (Fire) will be a man who will come out crawling, and his Lord will say to him, 'Enter Paradise.' He will reply, 'O Lord, Paradise is full.' Allah will give him the same order thrice, and each time the man will give Him the same reply, i.e., 'Paradise is full.' Thereupon Allah will say (to him), 'Ten times of the world is for you.' "
