Narrated `Abdullah bin Qais Al-Ash`ari:
The Prophet (ﷺ) said, "A tent (in Paradise) is like a hollow pearl which is thirty miles in height and on every corner of the tent the believer will have a family that cannot be seen by the others." (Narrated Abu `Imran in another narration, "The tent is sixty miles in height.")
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.
