Silver

And if it were not that the people would become one community [of disbelievers],¹ We would have made for those who disbelieve in the Most Merciful - for their houses - ceilings and stairways of silver upon which to mount.

And for their houses - doors and couches [of silver] upon which to recline

And there will be circulated among them vessels of silver and cups having been [created] clear [as glass],

Clear glasses [made] from silver of which they have determined the measure.

Upon them [i.e., the inhabitants] will be green garments of fine silk and brocade. And they will be adorned with bracelets of silver, and their Lord will give them a purifying drink.
