(9) باب فِي صِفَةِ خِيَامِ الْجَنَّةِ وَمَا لِلْمُؤْمِنِينَ فِيهَا مِنَ الأَهْلِينَ
Abu Bakr b. Abdullah b. Qais reported on the authority of his father that Allah's Messenger (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.
