Surah Al-'Ankabut — Ayah 64 (29:64)
وَمَا هَٰذِهِ ٱلۡحَيَوٰةُ ٱلدُّنۡيَآ إِلَّا لَهۡوٞ وَلَعِبٞۚ وَإِنَّ ٱلدَّارَ ٱلۡأٓخِرَةَ لَهِيَ ٱلۡحَيَوَانُۚ لَوۡ كَانُواْ يَعۡلَمُونَ ٦٤
English translation (Saheeh International)
And this worldly life is not but diversion and amusement. And indeed, the home of the Hereafter - that is the [eternal] life, if only they knew.
Brief commentary
This worldly life with all its temptations and enjoyments, is only amusement and play for those who are attached to it; it will expire quickly. Indeed, the abode of the afterlife is the real life, due to it being eternal. If only they knew, they would not have given preference to that which is temporary, over that which is eternal.
