Sura al-Zumar 39:20

لَٰكِنِ ٱلَّذِينَ ٱتَّقَوْا۟ رَبَّهُمْ لَهُمْ غُرَفٌ مِّن فَوْقِهَا غُرَفٌ مَّبْنِيَّةٌ تَجْرِى مِن تَحْتِهَا ٱلْأَنْهَٰرُ وَعْدَ ٱللَّـهِ لَا يُخْلِفُ ٱللَّـهُ ٱلْمِيعَادَ

lākini lladhīna ittaqaw rabbahum lahum ghurafun min fawqihā ghurafun mabniyyatun tajrī min taḥtihā l-anhāru waʿda allāhi lā yukhlifu allāhu l-mīʿāda

But it is for those who fear their Lord. That lofty mansions, one above another, have been built: beneath them flow rivers (of delight): (such is) the Promise of Allah: never doth Allah fail in (His) promise.
