﴿ فَذَرْهُمْ يَخُوضُوا۟ وَيَلْعَبُوا۟ حَتَّىٰ يُلَٰقُوا۟ يَوْمَهُمُ ٱلَّذِى يُوعَدُونَ ﴾

“But leave them to indulge in idle talk and play [with words] until they face that [Judgment] Day of theirs which they have been promised:”

So leave them to indulge their falsehoods and play in this world of theirs until they encounter that day of theirs which they are promised chastisement in and that is the Day of Resurrection.
