Sura al-Aʿrāf 7:51

ٱلَّذِينَ ٱتَّخَذُوا۟ دِينَهُمْ لَهْوًا وَلَعِبًا وَغَرَّتْهُمُ ٱلْحَيَوٰةُ ٱلدُّنْيَا فَٱلْيَوْمَ نَنسَىٰهُمْ كَمَا نَسُوا۟ لِقَآءَ يَوْمِهِمْ هَٰذَا وَمَا كَانُوا۟ بِـَٔايَٰتِنَا يَجْحَدُونَ

lladhīna ittakhadhū dīnahum lahwan wa-laʿiban wa-gharrathumu l-ḥayātu l-dunyā fa-l-yawma nansahum ka-mā nasū liqāʾa yawmihim hādhā wa-mā kānū bi-āyātinā yajḥadūna

"Such as took their religion to be mere amusement and play, and were deceived by the life of the world." That day shall We forget them as they forgot the meeting of this day of theirs, and as they were wont to reject Our signs.
