Divine promises and their fulfillment

وَٱقْتَرَبَ ٱلْوَعْدُ ٱلْحَقُّ فَإِذَا هِىَ شَـٰخِصَةٌ أَبْصَـٰرُ ٱلَّذِينَ كَفَرُوا۟ يَـٰوَيْلَنَا قَدْ كُنَّا فِى غَفْلَةٍ مِّنْ هَـٰذَا بَلْ كُنَّا ظَـٰلِمِينَ

And [when] the true promise [i.e., the resurrection] has approached; then suddenly the eyes of those who disbelieved will be staring [in horror, while they say], "O woe to us; we had been unmindful of this; rather, we were wrongdoers."

لَّهُمْ فِيهَا مَا يَشَآءُونَ خَـٰلِدِينَ ۚ كَانَ عَلَىٰ رَبِّكَ وَعْدًا مَّسْـُٔولًا

For them therein is whatever they wish, [while] abiding eternally. It is ever upon your Lord a promise [worthy to be] requested.
