Abu Bakr b. Abdullah b. Qais reported on the authority of his father that Messenger of Allah ﷺ 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.  

عَنِ النَّبِيِّ ﷺ قَالَ إِنَّ لِلْمُؤْمِنِ فِي الْجَنَّةِ لَخَيْمَةً مِنْ لُؤْلُؤَةٍ وَاحِدَةٍ مُجَوَّفَةٍ طُولُهَا سِتُّونَ مِيلاً لِلْمُؤْمِنِ فِيهَا أَهْلُونَ يَطُوفُ عَلَيْهِمُ الْمُؤْمِنُ فَلاَ يَرَى بَعْضُهُمْ بَعْضًا  

"لِلمُؤمِنِ في الْجَنَّةِ خَيمَةٌ مِنْ لُؤلُؤَةٍ مُجَوَّفَةٍ طولُهَا سِتُّونَ مِيلًا، لِلعَبْدِ الْمُؤمِنِ فِيهَا أَهْلٌ يَطُوفُ عَلَيهِمْ، لَا يَرَى بَعْضُهُمْ بَعْضًا".
