لٰكِنِ الَّذِیْنَ اتَّقَوْا رَبَّهُمْ لَهُمْ غُرَفٌ مِّنْ فَوْقِهَا غُرَفٌ مَّبْنِیَّةٌ ۙ تَجْرِیْ مِنْ تَحْتِهَا الْاَنْهٰرُ ؕ۬ وَعْدَ اللّٰهِ ؕ لَا یُخْلِفُ اللّٰهُ الْمِیْعَادَ ۟

Saheeh International
But those who have feared their Lord - for them are chambers, above them chambers built high, beneath which rivers flow. [This is] the promise of Allāh. Allāh does not fail in [His] promise.
Al-Mukhtasar fi Tafsir
But those who are mindful of their Lord, by fulfilling His instructions and avoiding His prohibitions, they will have lofty dwellings, one above the other, underneath which rivers flow. Allah has made a firm promise of this to them and Allah does not break His promise. He is far above that.
