quran:7:51 –

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.  

those who took their religion for a diversion and a game, and whom the life of this world has deluded.’ Therefore today We have forgotten them, We have left them in the Fire, just as they forgot the encounter of this day of theirs, when they neglected to perform ˹good˺ deeds for it, and because they used to deny Our signs.
القرآن:٧:٥١ –

الَّذِينَ اتَّخَذُوا دِينَهُمْ لَهْوًا وَلَعِبًا وَغَرَّتْهُمُ الْحَيَاةُ الدُّنْيَا ۚ فَالْيَوْمَ نَنْسَاهُمْ كَمَا نَسُوا لِقَاءَ يَوْمِهِمْ هَٰذَا وَمَا كَانُوا بِآيَاتِنَا يَجْحَدُونَ  

{الذين اتخذوا دينهم لهوا ولعبا وغرتهم الحياة الدنيا فاليوم ننساهم} نتركهم في النار {كما نسوا لقاء يومهم هذا} بتركهم العمل له {وما كانوا بآياتنا يجحدون} أي وكما جحدوا.
