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 صلى الله عليه وسلم قَالَ ‏"‏ فِي الْجَنَّةِ خَيْمَةٌ مِنْ لُؤْلُؤَةٍ مُجَوَّفَةٍ عَرْضُهَا سِتُّونَ مِيلاً فِي كُلِّ زَاوِيَةٍ مِنْهَا أَهْلٌ مَا يَرَوْنَ الآخَرِينَ يَطُوفُ عَلَيْهِمُ الْمُؤْمِنُ ‏"‏ ‏.‏

Abu Bakr b. Abdullah b. Qais reported on the authority of his father that Allah's Messenger (PBUH) 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.
