Quran 29:64 from Surah Al-Ankaboot on Divine Marvels.
وَمَا هَٰذِهِ ٱلۡحَيَوٰةُ ٱلدُّنۡيَآ إِلَّا لَهۡوٞ وَلَعِبٞۚ وَإِنَّ ٱلدَّارَ ٱلۡأٓخِرَةَ لَهِيَ ٱلۡحَيَوَانُۚ لَوۡ كَانُواْ يَعۡلَمُونَ
English translation: And not (is) this life (of) the world but amusement and play And indeed the Home (of) the Hereafter surely it (is) the life if only they know
Transliteration: wama hadhihi al-hayatu al-dun'ya illa lahwun wala'ibun wa-inna al-dara al-akhirata lahiya al-hayawanu law kanu ya'lamuna
