It was narrated from Ibn Masud Ra that the Messenger of Allah (pbuh) said: ” The last one to enter Paradise will be a man who will walk once, stumble once and be burned by the Fire once. When he gets passed it, he will turn to it and say: “Blessed be the One Who has saved me from you. Allah has given me something that he has not given to the first and the last”.
A tree will be raised up for him and he will say: “O Lord, bring me closer to that tree so that I might find shelter in its shade and drink of its water”. Allah the Mighty and Sublime will say: ” O son of Adam As, perhaps if I gave you that, you will ask Me for something else”. He will say: ” No, O Lord”, and he will promise that he will not ask Him for anything else, and His Lord, the Most High, will excuse him because he has seen something that he cannot help wanting. So he will be brought near to it and he will take shelter in its shade and drink of its water.
Then another tree will be raised up for him that is more beautiful than the first, and he will say: ” O Lord, bring me closer to this tree so that I might drink of its water and take shelter in its shade, and I will not ask for anything else”. He (Allah) will say: ” O son of Adam As, did you not promise Me that you would not ask Me for anything else?`. He will say: ” Perhaps if I bring you close to it you will ask Me for something else? He will promise that he will not ask Him for anything else, and his Lord, the Most High, will excuse him because he has seen something he cannot help wanting. So he will be brought near to it and he will take shelter in its shade and drink of its water.
Then another tree will be raised up for him at the gate of Paradise that is more beautiful than the first two. He will say: “O Lord, bring me closer to this tree so that I might take shelter in its shade and drink of its water, and I will not ask You for anything else”. He (Allah) will say: ” O son of Adam As, did you not promise Me that you would not ask Me of anything else?`. He will say: ” No, O Lord, I will not ask You for anything else?`. His Lord, the Most High, will excuse him because he has seen something that he cannot help wanting.
He will be brought close to it, and when he draws close to it, he will hear the voices of the people of Paradise and will say: ” O Lord, admit me therein”. He (Allah) will say: ” O son of Adam As, what will make you stop asking?`. Will it please you if I gave you the world and as much again?`. He will say: ” O Lord, are you making fun of me when you are the Lord of the Worlds?`.
Ibn Masud Ra laughed and said: ” Why don`t you ask me why I am laughing?`. They said: ” Why are you laughing?`. He (Ibn Masud Ra) said: ” This is how the Messenger of Allah (pbuh) laughed and they said: ” Why are you laughing, O Messenger of Allah?`. He (pbuh) said: ” Because the Lord of the Worlds will laugh when He says: “Are you making fun of me while you are the Lord of the Worlds?`. And He (Allah) will say: “I am not making fun of you, bu I am Able to do whatever I will”. (Muslim, Sahih).
