Hadith on Paradise: Lowest in Paradise has all desires fulfilled

Abu Huraira reported: The Messenger of Allah, peace and blessings be upon him, said, “Verily, the lowest in position among you in Paradise will have it said to him: Have whatever you desire. He will express his desires again and again. It will be said: Have your desires been satisfied? He will say yes. It will be said: For you is whatever you desire and more along with it.”

عَنْ أَبِي هُرَيْرَةَ عَنْ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ َقَالَ إِنَّ أَدْنَى مَقْعَدِ أَحَدِكُمْ مِنْ الْجَنَّةِ أَنْ يَقُولَ لَهُ تَمَنَّ فَيَتَمَنَّى وَيَتَمَنَّى فَيَقُولُ لَهُ هَلْ تَمَنَّيْتَ فَيَقُولُ نَعَمْ فَيَقُولُ لَهُ فَإِنَّ لَكَ مَا تَمَنَّيْتَ وَمِثْلَهُ مَعَهُ
