﴿ لَهُمُ ٱلْبُشْرَىٰ فِى ٱلْحَيَوٰةِ ٱلدُّنْيَا وَفِى ٱلْءَاخِرَةِ ۚ لَا تَبْدِيلَ لِكَلِمَٰتِ ٱللَّهِ ۚ ذَٰلِكَ هُوَ ٱلْفَوْزُ ٱلْعَظِيمُ ﴾

“For them there is the glad tiding [of happiness] in the life of this world and in the life to come; [and since] nothing could ever alter [the outcome of] God's promises, this, this is the triumph supreme!”

Theirs are good tidings in the life of this world in a hadīth verified by al-Hākim this has been explained as referring to a propitious vision which an individual might have or a vision which another might have of that person; and in the Hereafter Paradise and reward. There is no changing the Words of God no failing of His promises; that mentioned is the supreme triumph.
