Surat Az-Zukhruf (Ornaments of gold) - الزخرف

وَلَوْلَآ أَن يَكُونَ ٱلنَّاسُ أُمَّةً وَٰحِدَةً لَّجَعَلْنَا لِمَن يَكْفُرُ بِٱلرَّحْمَٰنِ لِبُيُوتِهِمْ سُقُفًا مِّن فِضَّةٍ وَمَعَارِجَ عَلَيْهَا يَظْهَرُونَ ﴿٣٣﴾

And were it not that all people had been a single nation, We would certainly have assigned to those who disbelieve in the Beneficent Allah (to make) of silver the roofs of their houses and the stairs by which they ascend.
