Sahih Muslim 182 c
Hammam b. Munabbih said:
This is what Abu Huraira transmitted to us from the Messenger of Allah (ﷺ), and he narrated many of them;- one of them was: The Messenger of Allah (ﷺ) said: The lowest in rank among you in Paradise would be asked: Desire (whatever you like). And he would express his desire and again and again express a desire. tHe would be asked: Have you expressed your desire? He would say: Yes. Then He (Allah) would say: For thee is (granted) what thou desirest, and the like of it along with it.
وَحَدَّثَنَا مُحَمَّدُ بْنُ رَافِعٍ، حَدَّثَنَا عَبْدُ الرَّزَّاقِ، أَخْبَرَنَا مَعْمَرٌ، عَنْ هَمَّامِ بْنِ مُنَبِّهٍ، قَالَ هَذَا مَا حَدَّثَنَا أَبُو هُرَيْرَةَ، عَنْ رَسُولِ اللَّهِ صلى الله عليه وسلم ‏.‏ فَذَكَرَ أَحَادِيثَ مِنْهَا وَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏
"‏ إِنَّ أَدْنَى مَقْعَدِ أَحَدِكُمْ مِنَ الْجَنَّةِ أَنْ يَقُولَ لَهُ تَمَنَّ ‏.‏ فَيَتَمَنَّى وَيَتَمَنَّى فَيَقُولُ لَهُ هَلْ تَمَنَّيْتَ فَيَقُولُ نَعَمْ ‏.‏ فَيَقُولُ لَهُ فَإِنَّ لَكَ مَا تَمَنَّيْتَ وَمِثْلَهُ مَعَهُ ‏"‏ ‏.‏
