Hadith 8168

وَقَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ : " إِنَّ أَدْنَى مَقْعَدِ أَحَدِكُمْ مِنَ الْجَنَّةِ أَنْ يَقُولَ لَهُ : تَمَنَّ وَيَتَمَنَّى ، فَيَقُولُ لَهُ : هَلْ تَمَنَّيْتَ ؟ فَيَقُولُ : نَعَمْ ، فَيَقُولُ لَهُ : فَإِنَّ لَكَ مَا تَمَنَّيْتَ وَمِثْلَهُ مَعَهُ " .
And the Prophet Muhammad (peace be upon him) said: The status of the person with the lowest rank in Paradise will be that it will be said to him, "Express your wishes." He will express his desires, then he will be asked, "Have all your wishes been fulfilled?" He will say, "Yes." Then it will be commanded, "Whatever wishes you have expressed will be granted to you, and an equal amount in addition will also be granted to you."
