It is narrated from Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "The last person to enter Paradise will be walking on the Bridge (Sirat), at times walking and at times falling on his face, while the Fire scorches him. When he has passed it, he will turn to look at it and say: Blessed is He who saved me from you; He has given me what He has not given anyone of the earlier or the later people. Then a tree will be raised up for him, and he will say: O my Lord! Bring me near to this tree so that I may rest in its shade and drink of its water. Allah, the Mighty and Majestic, will say: O son of Adam! Perhaps if I give you this, you will ask Me for something else. So He will bring him near to it, while his Lord knows that he will do so, and he will rest in its shade and drink of its water. Then another tree will be raised up for him, more beautiful than the first. He will say: O my Lord! Bring me near to it so that I may rest in its shade and drink of its water, and I will not ask You for anything besides it. And his Lord knows that he will do so, because he will be seeing something he cannot bear to resist. Allah, the Mighty and Majestic, will say: O son of Adam! Did you not make a covenant with Me that you would not ask for anything besides it? He will say: Yes, O my Lord, but this one - I will not ask You for anything besides it. And his Lord knows that he will do so, and He excuses him, because he will be seeing something he cannot bear to resist. Allah, the Mighty and Majestic, will say: Perhaps if I bring you near to it, you will ask Me for something else. He will make a covenant that he will not, so Allah will bring him near to it, and he will rest in its shade and drink of its water. Then a tree will be raised up for him by the gate of Paradise, more beautiful than the first two. He will say: O my Lord! Bring me near to this one, so that I may rest in its shade and drink of its water. Allah, Exalted be His mention, will say: O son of Adam! Did you not make a covenant with Me that you would not ask for anything besides it? He will say: O my Lord! This one - I will not ask You for anything besides it. Allah will say: Perhaps if I bring you near to it, you will ask Me for something else. He will make a covenant that he will not, while his Lord knows that he will do so, and his Lord excuses him, because he will be seeing something he cannot bear to resist. So Allah will bring him near to it, and he will hear the voices of the people of Paradise and say: O my Lord! Admit me into it. Allah will say: O son of Adam! Are you content that I give you the world and another like it along with it? He will say: Are You mocking me, when You are the Lord of the worlds?"
The narrator said: Hearing this, the Messenger of Allah (peace and blessings be upon him) laughed, then said: "Will you not ask me why I laughed?" The Companions said: "O Messenger of Allah! Why did you laugh?" He (peace and blessings be upon him) said: "(I laughed) at the laughter of the Lord of the worlds, the Blessed and Exalted, when he said: Are You mocking me, when You are the Lord of the worlds? Allah will say: No, I am not mocking, but I am able to do whatever I will."
