صحيح مسلم

Anas b. Malik reported that Allah's Messenger (ﷺ) said that one amongst the denizens of Hell who had led a life of ease and plenty amongst the people of the world would be made to dip in Fire only once on the Day of Resurrection and then it would be said to him: O, son of Adam, did you find any comfort, did you happen to get any material blessing? He would say: By Allah, no, my Lord. And then that person from amongst the persons of the world be brought who had led the most miserable life (in the world) from amongst the inmates of Paradise. and he would be made to dip once in Paradise and it would be said to him. 0, son of Adam, did you face, any hardship? Or had any distress fallen to your lot? And he would say: By Allah, no,0 my Lord, never did I face any hardship or experience any distress.
