ٱلَّذِينَ ٱتَّخَذُوا۟ دِينَهُمْ لَهْوًۭا وَلَعِبًۭا وَغَرَّتْهُمُ ٱلْحَيَوٰةُ ٱلدُّنْيَا ۚ فَٱلْيَوْمَ نَنسَىٰهُمْ كَمَا نَسُوا۟ لِقَآءَ يَوْمِهِمْ هَٰذَا وَمَا كَانُوا۟ بِـَٔايَٰتِنَا يَجْحَدُونَ
Who took their religion for a sport and pastime, and whom the life of the world beguiled. So this day We have forgotten them even as they forgot the meeting of this their Day and as they used to deny Our tokens.
Surah Al-A'raaf(7:51)
