Sahih al-Bukhari 3245
Beginning of Creation
The characteristics of Paradise, and the fact that it has already been created
Narrated Abu Huraira: Allah's Messenger (ﷺ) said, "The first group (of people) who will enter Paradise will be (glittering) like the moon when it is full. They will not spit or blow their noses or relieve nature. Their utensils will be of gold and their combs of gold and silver; in their centers the aloe wood will be used, and their sweat will smell like musk. Everyone of them will have two wives; the marrow of the bones of the wives' legs will be seen through the flesh out of excessive beauty. They ( i.e. the people of Paradise) will neither have differences nor hatred amongst themselves; their hearts will be as if one heart and they will be glorifying Allah in the morning and in the evening."
