Chapter 9, Verse 55, Repentance
سورة التوبة
فَلَا تُعۡجِبۡكَ أَمۡوَٰلُهُمۡ وَلَآ أَوۡلَٰدُهُمۡۚ إِنَّمَا يُرِيدُ ٱللَّهُ لِيُعَذِّبَهُم بِهَا فِي ٱلۡحَيَوٰةِ ٱلدُّنۡيَا وَتَزۡهَقَ أَنفُسُهُمۡ وَهُمۡ كَٰفِرُونَ
So let not their wealth or their children amaze you (O Muhammad ﷺ); in reality Allah's Plan is to punish them with these things in the life of the this world, and that their souls shall depart (die) while they are disbelievers.
Chapter 18, Verse 46, The cave
سورة الكهف
ٱلۡمَالُ وَٱلۡبَنُونَ زِينَةُ ٱلۡحَيَوٰةِ ٱلدُّنۡيَاۖ وَٱلۡبَٰقِيَٰتُ ٱلصَّٰلِحَٰتُ خَيۡرٌ عِندَ رَبِّكَ ثَوَابٗا وَخَيۡرٌ أَمَلٗا
wealth and children are the adornment of the life of this world. But the good righteous deeds (five compulsory prayers, deeds of Allah's obedience, good and nice talk, remembrance of Allah with glorification, praises and thanks, etc.), that last, are better with your Lord for rewards and better in respect of hope.
Chapter 28, Verse 60, The Story
سورة القصص
وَمَآ أُوتِيتُم مِّن شَيۡءٖ فَمَتَٰعُ ٱلۡحَيَوٰةِ ٱلدُّنۡيَا وَزِينَتُهَاۚ وَمَا عِندَ ٱللَّهِ خَيۡرٞ وَأَبۡقَىٰٓۚ أَفَلَا تَعۡقِلُونَ
and whatever you have been given is an enjoyment of the life of (this) world and its adornment, and that (Hereafter) which is with Allah is better and will remain forever. Have you then no sense?
Chapter 57, Verse 20, The Iron
سورة الحديد
ٱعۡلَمُوٓاْ أَنَّمَا ٱلۡحَيَوٰةُ ٱلدُّنۡيَا لَعِبٞ وَلَهۡوٞ وَزِينَةٞ وَتَفَاخُرُۢ بَيۡنَكُمۡ وَتَكَاثُرٞ فِي ٱلۡأَمۡوَٰلِ وَٱلۡأَوۡلَٰدِۖ كَمَثَلِ غَيۡثٍ أَعۡجَبَ ٱلۡكُفَّارَ نَبَاتُهُۥ ثُمَّ يَهِيجُ فَتَرَىٰهُ مُصۡفَرّٗا ثُمَّ يَكُونُ حُطَٰمٗاۖ وَفِي ٱلۡأٓخِرَةِ عَذَابٞ شَدِيدٞ وَمَغۡفِرَةٞ مِّنَ ٱللَّهِ وَرِضۡوَٰنٞۚ وَمَا ٱلۡحَيَوٰةُ ٱلدُّنۡيَآ إِلَّا مَتَٰعُ ٱلۡغُرُورِ
Know that the life of this world is only play and amusement, pomp and mutual boasting among you, and rivalry in respect of wealth and children, as the likeness of vegetation after rain, thereof the growth is pleasing to the tiller; afterwards it dries up and you see it turning yellow; then it becomes straw. But in the Hereafter (there is) a severe torment (for the disbelievers, evil-doers), and (there is) Forgiveness from Allah and (His) Good Pleasure (for the believers, good-doers), whereas the life of this world is only a deceiving enjoyment.
Chapter 3, Verse 14, The family of Imran
سورة آل عمران
زُيِّنَ لِلنَّاسِ حُبُّ ٱلشَّهَوَٰتِ مِنَ ٱلنِّسَآءِ وَٱلۡبَنِينَ وَٱلۡقَنَٰطِيرِ ٱلۡمُقَنطَرَةِ مِنَ ٱلذَّهَبِ وَٱلۡفِضَّةِ وَٱلۡخَيۡلِ ٱلۡمُسَوَّمَةِ وَٱلۡأَنۡعَٰمِ وَٱلۡحَرۡثِۗ ذَٰلِكَ مَتَٰعُ ٱلۡحَيَوٰةِ ٱلدُّنۡيَاۖ وَٱللَّهُ عِندَهُۥ حُسۡنُ ٱلۡمَـَٔابِ
Beautified for men is the love of things they covet; women, children, much of gold and silver (wealth), branded beautiful horses, cattle and well-tilled land. this is the pleasure of the present world's life; but Allah has the excellent return (Paradise with flowing rivers, etc.) with Him.
