Surah Yunus, ayah 64

10:64

لَهُمُ ٱلۡبُشۡرَىٰ فِي ٱلۡحَيَوٰةِ ٱلدُّنۡيَا وَفِي ٱلۡأٓخِرَةِۚ لَا تَبۡدِيلَ لِكَلِمَٰتِ ٱللَّهِۚ ذَٰلِكَ هُوَ ٱلۡفَوۡزُ ٱلۡعَظِيمُ ٦٤

Lahumul-bushrā fil-hayawātid-dunyā wafil-ākhirati lā tabdīla likalimātillāhi dhālika huwal-fawzul-'azīm

For them are good tidings in the worldly life and in the Hereafter. No change is there in the words [i.e., decrees] of Allāh. That is what is the great attainment.
