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 a tent made of a single hollowed pearl, the breadth of which would be sixty miles from all sides and there would live a family in each corner and the other would not be able to see the believer who goes around them.

وَحَدَّثَنِي أَبُو غَسَّانَ الْمِسْمَعِيُّ، حَدَّثَنَا أَبُو عَبْدِ الصَّمَدِ، حَدَّثَنَا أَبُو عِمْرَانَ الْجَوْنِيُّ،
عَنْ أَبِي بَكْرِ بْنِ عَبْدِ اللَّهِ بْنِ قَيْسٍ، عَنْ أَبِيهِ، أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ
"
فِي الْجَنَّةِ خَيْمَةٌ مِنْ لُؤْلُؤَةٍ مُجَوَّفَةٍ عَرْضُهَا سِتُّونَ مِيلاً فِي كُلِّ زَاوِيَةٍ مِنْهَا أَهْلٌ مَا يَرَوْنَ
الآخَرِينَ يَطُوفُ عَلَيْهِمُ الْمُؤْمِنُ " .
