Quran 43:83 from Surah Az-Zukhruf on Divine Marvels.
فَذَرۡهُمۡ يَخُوضُواْ وَيَلۡعَبُواْ حَتَّىٰ يُلَٰقُواْ يَوۡمَهُمُ ٱلَّذِي يُوعَدُونَ
English translation: So leave them (to) converse vainly and play until they meet their Day which they are promised
Transliteration: fadharhum yakhudu wayal'abu hatta yulaqu yawmahumu alladhi yu'aduna
