(Az-Zukhuruf) 43 : 83
فَذَرْهُمْ يَخُوضُوا وَيَلْعَبُوا حَتَّىٰ يُلَاقُوا يَوْمَهُمُ الَّذِي يُوعَدُونَ
So you leave them in mocking and playing until they meet their day which they have been promised.
Today the true disbelievers mentioned in verses 4: 150-151 are considering their life as play and amusement as explained in verses 7: 50-51. So the odd believer is commanded to leave these Fujjar in their mockery and play, and to do jihad against them with Adhikr as explained in verses 9: 73; and 25: 52. See explanation 9: 28, 123; and 40: 82-85.
