Narrated By ‘Abdullah bin Qais : The Prophet 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).”
