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.

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