This quote originates from the novel 'The Brothers Karamazov' written by Fyodor Dostoevsky. It suggests that while humanity has made advancements in acquiring material possessions, it has simultaneously experienced a decline in overall happiness and joy. It's a commentary on the potential downsides of focusing solely on accumulating wealth and material goods, rather than on broader aspects of human well-being. Allah says in Quran: اعْلَمُوا أَنَّمَا الْحَيَاةُ الدُّنْيَا لَعِبٌ وَلَهْوٌ وَزِينَةٌ وَتَفَاخُرٌ بَيْنَكُمْ وَتَكَاثُرٌ فِي الْأَمْوَالِ وَالْأَوْلَادِ ۖ كَمَثَلِ غَيْثٍ أَعْجَبَ الْكُفَّارَ نَبَاتُهُ ثُمَّ يَهِيجُ فَتَرَاهُ مُصْفَرًّا ثُمَّ يَكُونُ حُطَامًا — وَمَا الْحَيَاةُ الدُّنْيَا إِلَّا مَتَاعُ الْغُرُورِ Know that the life of this world is but amusement and diversion and adornment and boasting to one another and competition in increase of wealth and children - like the example of a rain whose [resulting] plant growth pleases the tillers; then it dries and you see it turned yellow; then it becomes [scattered] debris. — And what is the worldly life except the enjoyment of delusion." Al-Quran 57:20 The Messenger of Allah (ﷺ) said, لَيْسَ الْغِنَى عَنْ كَثْرَةِ الْعَرَضِ وَلَكِنَّ الْغِنَى غِنَى النَّفْسِ ‏ Wealth is not in having many possessions, but wealth is the richness of the soul (contentment). (Sahih al-Bukhari 6446, Sahih Muslim 1051)
