quran:21:2 –

No mention comes to them anew from their Lord except that they listen to it while they are at play  

There does not come to them any new reminder from their Lord, ˹revealed˺ gradually, in other words, ˹new˺ words of the Qur’ān, but they listen to it as they play, ˹as they˺ engage in mockery,
القرآن:٢١:٢ –

مَا يَأْتِيهِمْ مِنْ ذِكْرٍ مِنْ رَبِّهِمْ مُحْدَثٍ إِلَّا اسْتَمَعُوهُ وَهُمْ يَلْعَبُونَ  

{ما يأتيهم من ذكر من ربهم محدث} شيئاً فشيئاً أي لفظ قرآن {إلا استمعوه وهم يلعبون} يستهزئون.

quran:26:5 –

And no revelation comes to them anew from the Most Merciful except that they turn away from it.  

And there would never come to them from the Compassionate One any remembrance, any ˹revelation from the˺ Qur’ān, that is new (muhdathin, is an explicative adjective) but that they used to disregard it.
القرآن:٢٦:٥ –

وَمَا يَأْتِيهِمْ مِنْ ذِكْرٍ مِنَ الرَّحْمَٰنِ مُحْدَثٍ إِلَّا كَانُوا عَنْهُ مُعْرِضِينَ  

{وما يأتيهم من ذكر} قرآن {من الرحمن مُحدّث} صفة كاشفة {إلا كانوا عنه معرضين}.
