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. (Using translation from Muslim 2838b)
عَنْ رَسُولِ اللهِ ﷺ أَنَّهُ قَالَ فِي الْجَنَّةِ خَيْمَةٌ مِنْ لُؤْلُؤَةٍ مُجَوَّفَةٍ عَرْضُهَا سِتُّونَ مِيلًا فِي كُلِّ زَاوِيَةٍ مِنْهَا أَهْلٌ مَا يَرَوْنَ الْآخَرِينَ يَطُوفُ عَلَيْهِمُ الْمُؤْمِنُ
