Chapter 54: The Book of Paradise, its Description, its Bounties and its Inhabitants
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 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.
