Surah Yunus (Jonah), Verse 64

لَهُمُ الْبُشْرٰی فِی الْحَیٰوةِ الدُّنْیَا وَفِی الْاٰخِرَةِ لَا تَبْدِیْلَ لِكَلِمٰتِ اللّٰهِ ذٰلِكَ هُوَ الْفَوْزُ الْعَظِیْمُ ۟

Lahumul bushraa fil hayaatid dunyaa wa fil Aakhirah; laa tabdeela li kalimaatil laah; zaalika huwal fawzul 'azeem

“For them are glad tidings, in the life of the present and in the Hereafter; no change can there be in the words of Allah. This is indeed the supreme felicity.”
