The last person to enter Paradise

'Abdullaah ibn Mas'oud reported that the Messenger of Allah (Saw) said: "The last person to enter paradise will be a man who will alternately walk, stagger and be touched by the Fire. Once he has passed out of the Fire, he will turn to face it and say, "Blessed be He Who has saved me from you. Allah (swt) has given me something that He did not give to the earlier and later generations. Then a tree will be raised up for him, and he will say, "O my Lord, bring me closer to this tree so that I may enjoy its shade and drink of its water". Allah may He be glorified, will say, "O son of Adam if I grant you this, will you ask Me for something else?" He will say, "No, ‘O Lord,”and he pleads that he will ask Him nothing. Allah (swt) will excuse him because he is seeing something that he has no patience to resist, so He will bring him closer and he will enjoy its shade and drink its water.

Then another tree, better than the first, will be raised up for him and he will say, "O my Lord, bring me near to this tree, so that I may drink its water and enjoy its shade, I will not ask you for anything more". Allah (swt) will say, "O son of Adam did you not promise Me that you would not ask me for anything else? He will further say may be that if I bring you closer to this tree you will ask for more?" The man will pledge not to ask for any more, and Allah will excuse him because he has no patience to resist, so He will bring him closer and he will enjoy its shade and drink its water.

Then a third tree will be raised up at the gate of paradise, and it will be better than the first two. The man will say, "O My Lord, bring me closer to this (tree) so that I may enjoy its shade and drink its water, and I will not ask for anything more." Allah will say, "O son of Adam, did you not promise Me that you would not ask Me for anything more?" He will say, "Yes, O Lord, I will not ask you for anything more." His Lord, may He be glorified, will excuse him because he has no patience to resist. He will bring him closer to this tree. When he is brought close, he will hear the voices of the people of Paradise, and will say, "O my Lord, admit me to it." Allah (swt) will say, "O son of Adam what do you want for sure so that you ask Me not anything else thereafter? Will it please you if I give you the world along with similar to that?" He will say, "O Lord, are You making fun of me when You are the Lord of the worlds?"

Ibn Mas'oud smiled and said, "Why do you not ask me why I am smiling?" They asked, "Why are you smiling?" He said, "Because the Messenger of Allah (Peace be upon him) smiled". They asked, "Why are you smiling, O Messenger of Allah (Peace be upon him)?" He said, "Because the Lord of the Worlds will smile when He is asked, "Are You making fun of me when You are the Lord of the Worlds?" He will say, "I am not making fun of you, but I am able to do whatever I will""".
