Surah Az-Zumar, ayah 20

لَٰكِنِ ٱلَّذِينَ ٱتَّقَوۡاْ رَبَّهُمۡ لَهُمۡ غُرَفٞ مِّن فَوۡقِهَا غُرَفٞ مَّبۡنِيَّةٞ تَجۡرِي مِن تَحۡتِهَا ٱلۡأَنۡهَٰرُۖ وَعۡدَ ٱللَّهِ لَا يُخۡلِفُ ٱللَّهُ ٱلۡمِيعَادَ ٢٠

Lākinil-ladhīnat-taqaw rabbahum lahum ghurafum min fawqihā ghurafum mabniyyatun tajrī min tahtihal-anhāru wa'dallāhi lā yukhlifullāhul-mī'ād

But those who have feared their Lord - for them are chambers,¹³⁴⁷ above them chambers built high, beneath which rivers flow. [This is] the promise of Allāh. Allāh does not fail in [His] promise.
