10:64
لَهُمُ ٱلْبُشْرَىٰ فِى ٱلْحَيَوٰةِ ٱلدُّنْيَا وَفِى ٱلْـَٔاخِرَةِ ۚ لَا تَبْدِيلَ لِكَلِمَـٰتِ ٱللَّهِ ۚ ذَٰلِكَ هُوَ ٱلْفَوْزُ ٱلْعَظِيمُ
lahumu l-bush'rā fī l-ḥayati l-dun'yā wafī l-ākhirati lā tabdīla likalimāti l-lahi dhālika huwa l-fawzu l-ʿaẓīmu
for them there is good news in this life and in the Hereafter- there is no changing the promises of God- that is truly the supreme triumph.
For them are glad tidings, in the life of the present world (i.e. through a righteous dream seen by the person himself or shown to others), and in the Hereafter. No change can there be in the Words of Allâh. This is indeed the supreme success.
