Quran 43.33-35
And were it not that mankind would have become one community, We might well have appointed, for those who disbelieve in the Beneficent, roofs of silver for their houses and stairs (of silver) whereby to mount, And for their houses doors (of silver) and couches of silver whereon to recline, And ornaments of gold. Yet all that would have been but a provision of the life of the world. And the Hereafter with your Lord would have been for those who keep from evil.
