'Abdullah b. Qais transmitted on the authority of his father (Abu Musa Ash'ari) that the Apostle (may peace be upon him) said: There would be two gardens (in Paradise) the vessels and contents of which would be of silver, and two gardens whose vessels and contents would be of gold. The only thing intervening to hinder the people from looking at their Lord will be the mantle of Grandeur over His face in the Garden of Eden.
