زُيِّنَ لِلنَّاسِ حُبُّ ٱلشَّهَوَٰتِ مِنَ ٱلنِّسَآءِ وَٱلْبَنِينَ وَٱلْقَنَٰطِيرِ ٱلْمُقَنطَرَةِ مِنَ ٱلذَّهَبِ وَٱلْفِضَّةِ وَٱلْخَيْلِ ٱلْمُسَوَّمَةِ وَٱلْأَنْعَٰمِ وَٱلْحَرْثِ ۗ ذَٰلِكَ مَتَٰعُ ٱلْحَيَوٰةِ ٱلدُّنْيَا ۖ وَٱللَّهُ عِندَهُۥ حُسْنُ ٱلْمَـَٔابِ
Beautified for mankind is love of the joys (that come) from women and offspring; and stored-up heaps of gold and silver, and horses branded (with their mark), and cattle and land. That is comfort of the life of the world. Allah! With Him is a more excellent abode.
Surah Aal-i-Imraan(3:14)
