From Sahih Bukhari (Hadith 4878):
Narrated `Abdullah bin Qais:Allah's Messenger (ﷺ) said, "Two gardens, the utensils and the contents of which are of silver, and two other gardens, the utensils and contents of which are of gold. And nothing will prevent the people who will be in the Garden of Eden from seeing their Lord except the curtain of Majesty over His Face
