﴿ ٱعْلَمُوٓا۟ أَنَّمَا ٱلْحَيَوٰةُ ٱلدُّنْيَا لَعِبٌۭ وَلَهْوٌۭ وَزِينَةٌۭ وَتَفَاخُرٌۢ بَيْنَكُمْ وَتَكَاثُرٌۭ فِى ٱلْأَمْوَٰلِ وَٱلْأَوْلَٰدِ ۖ كَمَثَلِ غَيْثٍ أَعْجَبَ ٱلْكُفَّارَ نَبَاتُهُۥ ثُمَّ يَهِيجُ فَتَرَىٰهُ مُصْفَرًّۭا ثُمَّ يَكُونُ حُطَٰمًۭا ۖ وَفِى ٱلْءَاخِرَةِ عَذَابٌۭ شَدِيدٌۭ وَمَغْفِرَةٌۭ مِّنَ ٱللَّهِ وَرِضْوَٰنٌۭ ۚ وَمَا ٱلْحَيَوٰةُ ٱلدُّنْيَآ إِلَّا مَتَٰعُ ٱلْغُرُورِ ﴾

“KNOW [O men] that the life of this world is but a play and a passing delight, and a beautiful show, and [the cause of] your boastful vying with one another, and [of your] greed for more and more riches and children. Its parable is that of [life-giving] rain: the herbage which it causes to grow delights the tillers of the soil; but then it withers, and thou canst see it turn yellow; and in the end it crumbles into dust. But [the abiding truth of man’s condition will become fully apparent] in the life to come: [either] suffering severe, or God’s forgiveness and His goodly acceptance: for the life of this world is nothing but an enjoyment of self-delusion.”
