Who will be the last person to enter Jannah (paradise)?

The answer to this question, originally posed by the companions, is answered in a number of ahadith: The last person to enter paradise will be a man who will walk once, stumble once and be burned by the Fire once. Once he gets past it, he will turn around and face it saying, 'Blessed be the One Who has saved me from you. God has given me something that He has not given to the first and the last.' (Muslim) The Messenger (saw) said: I know the person who will be the last to come out of the (Hell) Fire, and the last to enter Paradise. He will be a man who will come out crawling and Allah will say to him, 'Go and enter Paradise.' He will go to it, but he will imagine that it had been filled, and then he will return and say, 'O Lord, I have found it full.' Allah will say, 'Go and enter Paradise, and you will have what equals the world and ten times as much (or, you will have as much as ten times the like of the world).' On that, the man will say, 'Do you mock at me (or laugh at me) though You are the King?' I saw Allah's Messenger (saw) (while saying that) smiling that his premolar teeth became visible. It is said that will be the lowest in degree amongst the people of Paradise. (Bukhari) When Allah has finished his judgment of the people, He will take whomever He will out of Hell through His mercy. He will then order the angels to take out of the Fire all those who used to worship none but Allah from among those whom Allah wanted to be merciful to and those who testified (in the world) that none has the right to be worshipped but Allah. The angels will recognize them in the Fire by the marks of prostration (on their foreheads), for the Fire will eat up all the human body except the mark caused by prostration as Allah has forbidden the Fire to eat the mark of prostration. They will come out of the Fire, completely burnt and then the water of life will be poured over them and they will grow under it as does a seed that comes in the mud of the torrent. Then Allah will finish the judgments among the people, and there will remain one man facing the (Hell) Fire and he will be the last person among the people of Hell to enter Paradise. He will say, 'O my Lord! Please turn my face away from the fire because its air has hurt me and its severe heat has burnt me.' So he will invoke Allah in the way Allah will wish him to invoke, and then Allah will say to him, 'If I grant you that, will you then ask for anything else?' He will reply, 'No, by Your Power, I will not ask You for anything else.' He will give his Lord whatever promises and covenants Allah will demand. So Allah will turn his face away from Fire. When he will face Paradise and will see it, he will remain quiet for as long as Allah will wish him to remain quiet, then he will say, 'O my Lord! Bring me near to the gate of Paradise.' Allah will say to him, 'Didn't you give your promises and covenants that you would never ask for anything more than what you had been given? Woe on you, O Adam's son! How treacherous you are!' He will say, 'O my lord,' and will keep on invoking Allah till He says to him, 'If I give what you are asking, will you then ask for anything else?' He will reply, 'No, by Your Power, I will not ask for anything else.' Then he will give covenants and promises to Allah and then Allah will bring him near to the gate of Paradise. When he stands at the gate of Paradise, Paradise will be opened and spread before him, and he will see its splendor and pleasures whereupon he will remain quiet as long as Allah will wish him to remain quiet, and then he will say, O my Lord! Admit me into Paradise.' Allah will say, 'Didn't you give your covenants and promises that you would not ask for anything more than what you had been given?' Allah will say, 'Woe on you, O Adam's son! How treacherous you are! ' The man will say, 'O my Lord! Do not make me the most miserable of Your creation,' and he will keep on invoking Allah till Allah will laugh because of his sayings, and when Allah will laugh because of him, He will say to him, 'Enter Paradise,' and when he will enter it, Allah will say to him, 'Wish for anything.' So he will ask his Lord, and he will wish for a great number of things, for Allah Himself will remind him to wish for certain things by saying, '(Wish for) so-and-so.' When there is nothing more to wish for, Allah will say, 'This is for you, and its equal (is for you) as well." Ata' bin Yazid added: Abu Sa'id Al-Khudri who was present with Abu Hurairah, did not deny whatever the latter said, but when Abu Hurairah said that Allah had said, "That is for you and its equal as well," Abu Sa'id Al-Khudri said, "And ten times as much, O Abu Hurairah!" Abu Hurairah said, "I do not remember, except his saying, 'That is for you and its equal as well.'" Abu Sa'id Al-Khudri then said, "I testify that I remember the Prophet (saw) saying, 'That is for you, and ten times as much.' ' Abu Hurairah then added, "That man will be the last person of the people of Paradise to enter Paradise." (Bukhari)
