Sahih Muslim , Book 53, Hadith 27 (In-Book) ⓘ

Abu Bakr b. Abdullah b. Qais reported on the authority of his father that Allah's Messenger said that in Paradise there would be for a believer a tent of a single hollowed pearl the breadth of which would be sixty miles. It would be meant for a believer and the believers would go around it and none would be able to see the others.

حَدَّثَنَا سَعِيدُ بْنُ مَنْصُورٍ، عَنْ أَبِي قُدَامَةَ، - وَهُوَ الْحَارِثُ بْنُ عُبَيْدٍ - عَنْ أَبِي، عِمْرَانَ الْجَوْنِيِّ عَنْ أَبِي بَكْرِ بْنِ عَبْدِ اللَّهِ بْنِ قَيْسٍ، عَنْ أَبِيهِ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ ‏ "‏ إِنَّ لِلْمُؤْمِنِ فِي الْجَنَّةِ لَخَيْمَةً مِنْ لُؤْلُؤَةٍ وَاحِدَةٍ مُجَوَّفَةٍ طُولُهَا سِتُّونَ مِيلاً لِلْمُؤْمِنِ فِيهَا أَهْلُونَ يَطُوفُ عَلَيْهِمُ الْمُؤْمِنُ فَلاَ يَرَى بَعْضُهُمْ بَعْضًا ‏" ‏ ‏.‏
