Quran 43:33

وَلَوۡلَآ أَن يَكُونَ ٱلنَّاسُ أُمَّةً۬ وَٲحِدَةً۬ لَّجَعَلۡنَا لِمَن يَكۡفُرُ بِٱلرَّحۡمَـٰنِ لِبُيُوتِہِمۡ سُقُفً۬ا مِّن فِضَّةٍ۬ وَمَعَارِجَ عَلَيۡہَا يَظۡهَرُونَ ٣٣

If it were not that all the people might become one (disbelieving) congregation, we would have granted everyone who disbelieves in The Most Gracious mansions with silver roofs, and stairs upon which they could climb.
