Verse 20

ٱعْلَمُوٓا۟ أَنَّمَا ٱلْحَيَوٰةُ ٱلدُّنْيَا لَعِبٌ وَلَهْوٌ وَزِينَةٌ وَتَفَاخُرٌۢ بَيْنَكُمْ وَتَكَاثُرٌ فِى ٱلْأَمْوَٰلِ وَٱلْأَوْلَـٰدِ كَمَثَلِ غَيْثٍ أَعْجَبَ ٱلْكُفَّارَ نَبَاتُهُۥ ثُمَّ يَهِيجُ فَتَرَىٰهُ مُصْفَرًّا ثُمَّ يَكُونُ حُطَـٰمًا وَفِى ٱلْـَٔاخِرَةِ عَذَابٌ شَدِيدٌ وَمَغْفِرَةٌ مِّنَ ٱللَّهِ وَرِضْوَٰنٌ وَمَا ٱلْحَيَوٰةُ ٱلدُّنْيَآ إِلَّا مَتَـٰعُ ٱلْغُرُورِ

You shall know that this worldly life is indeed nothing but play and amusement and vanities, boasting and hoarding of money and producing many children. This is the example of the rain delighting the unfaithful as it grew their crops and then they saw it turning yellow and turned into hay.  In the Hereafter there is either ultimate suffering or forgiveness from God and approval.  And this worldly life is nothing but enjoyment of an illusion.
