﴿ مَا يَأْتِيهِم مِّن ذِكْرٍۢ مِّن رَّبِّهِم مُّحْدَثٍ إِلَّا ٱسْتَمَعُوهُ وَهُمْ يَلْعَبُونَ ﴾

“Whenever there comes unto them any new re­minder from their Sustainer, they but listen to it with playful amusement,”

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
