مَا يَأْتِيهِم مِّن ذِكْرٍ مِّن رَّبِّهِم مُّحْدَثٍ إِلَّا اسْتَمَعُوهُ وَهُمْ يَلْعَبُونَ (2)
(21:2) They give a mere formal hearing to every new Revelation *3 that comes to them from their Lord and remain engaged in the game (of life) for their hearts are preoccupied (with other matters.) *4
*3) "New Revelation": A new Surah of the Qur'an.
*4) The words of the original Text may also be interpreted as: "They do not take life seriously but treat it as a sport and a joke".
