43:83
فَذَرْهُمْ يَخُوضُوا۟ وَيَلْعَبُوا۟ حَتَّىٰ يُلَـٰقُوا۟ يَوْمَهُمُ ٱلَّذِى يُوعَدُونَ
fadharhum yakhūḍū wayalʿabū ḥattā yulāqū yawmahumu alladhī yūʿadūna
Leave them to wade in deeper and play about, until they face the Day they have been promised.
So leave them (alone) to speak nonsense and play until they meet the Day of theirs which they have been promised.
