Prophetic Commentary on the Qur'an (Tafseer of the Prophet (pbuh))
Bukhari :: Book 6 :: Volume 60 :: Hadith 402
Narrated Abdullah bin Qais:
Allah's Apostle said, "In Paradise there is a pavilion made of a single hollow pearl sixty miles wide, in each corner of which there are wives who will not see those in the other corners; and the believers will visit and enjoy them. And there are two gardens, the utensils and contents of which are made of silver; and two other gardens, the utensils and contents of which are made of so-and-so (i.e. gold) and nothing will prevent the people staying in the Garden of Eden from seeing their Lord except the curtain of Majesty over His Face."
