﴿ فَلَمَّا نَسُوا۟ مَا ذُكِّرُوا۟ بِهِۦ فَتَحْنَا عَلَيْهِمْ أَبْوَٰبَ كُلِّ شَىْءٍ حَتَّىٰٓ إِذَا فَرِحُوا۟ بِمَآ أُوتُوٓا۟ أَخَذْنَٰهُم بَغْتَةًۭ فَإِذَا هُم مُّبْلِسُونَ ﴾

“Then, when they had forgotten all that they had been told to take to heart, We threw open to them the gates of all [good] things until -even as they were rejoicing in what they had been granted - We suddenly took them to task: and lo! they were broken in spirit;”
