Surah Al-A'raf, ayah 51

7:51

ٱلَّذِينَ ٱتَّخَذُواْ دِينَهُمۡ لَهۡوٗا وَلَعِبٗا وَغَرَّتۡهُمُ ٱلۡحَيَوٰةُ ٱلدُّنۡيَاۚ فَٱلۡيَوۡمَ نَنسَىٰهُمۡ كَمَا نَسُواْ لِقَآءَ يَوۡمِهِمۡ هَٰذَا وَمَا كَانُواْ بِـَٔايَٰتِنَا يَجۡحَدُونَ ٥١

Alladhīnat-takhadhū dīnahum lahwan wala'iban wagharrathumul-hayawātud-dunyā fal-yawma nansāhum kamā nasū liqā'a yawmihim hādhā wamā kānū bi'āyātinā yajhadūn

Who took their religion as distraction and amusement and whom the worldly life deluded." So today We will forget them just as they forgot the meeting of this Day of theirs and for having rejected Our verses.
