question #3 Sahih al-Bukhari 7444, Book 97, Hadith 70 : How are the concepts of silver and gold used to describe the rewards in Paradise?

The Prophet (ﷺ) said, “(There will be) two Paradises of silver and all the utensils and whatever is therein
(will be of silver); and two Paradises of gold, and its utensils and whatever therein (will be of gold),
and there will be nothing to prevent the people from seeing their Lord except the Cover of Majesty
over His Face in the Paradise of Eden (eternal bliss).
