Hadith: Verily, the lowest place of any of you in Paradise will be that Allah will tell him to express his wish. He will wish and wish again. Allah will then ask him: Have you expressed your wish? He will answer: Yes, I have. Allah will say: You will have what you have wished for and the like thereof along with it

عن أبي هريرة رضي الله عنه أن رسول الله صلى الله عليه وسلم قال: «إنَّ أدنى مَقْعَدِ أحدِكم من الجنة أن يقول له: تَمَنَّ، فيتمنَّى ويتمنَّى فيقول له: هل تمنَّيتَ؟ فيقول: نعم، فيقول له: فإن لك ما تمنَّيتَ ومثله معه».
[صحيح] - [رواه مسلم]

Abu Hurayrah (may Allah be pleased with him) reported that the Prophet (may Allah's peace and blessings be upon him) said: "Verily, the lowest place of any of you in Paradise will be that Allah will tell him to express his wish. He will wish and wish again. Allah will then ask him: 'Have you expressed your wish?' He will answer: 'Yes, I have.' Allah will say: 'You will have what you have wished for and the like thereof along with it.'"
[Authentic hadith] - [Narrated by Muslim]

Explanation

The person who will have the lowest place in Paradise will be the one who will receive all of his wishes, such that none of his wishes will be left unfulfilled. Allah will say to him: "Wish for anything", so he will wish for everything he wants, until, when he had wished for everything he wants, Allah will say to him: Verily, you will receive that which you wished for and the like thereof', as an increase, blessing and generous gift from Allah, the Almighty.
