Musnad Abu Ya'la al-Mawsili 117:247

Zuhayr narrated to us, Affan narrated to us, Hammad bin Salamah narrated to us, Thabit informed us, from Anas, that the Messenger of Allah (may Allah bless him and grant him peace) said: "The person who had the most severe trial in the world among the people of Paradise will be brought, and Allah will say: 'Dip him a dip into Paradise.' So he will be dipped into it a dip, and then Allah will say: 'O son of Adam, have you ever seen any misery or anything you disliked?' He will say: 'No, by Your Might, I have never seen anything I disliked.' Then the person who had the most luxury in the world among the people of the Fire will be brought, and Allah will say: 'Dip him a dip into the Fire.' So he will be dipped into it a dip. He said: 'Then He will say: O son of Adam, have you ever seen any good or any delight of the eye?' He will say: 'No, by Your Might, I have never seen any good or any delight of the eye.'"
