وَلَا يَحْسَبَنَّ ٱلَّذِينَ يَبْخَلُونَ بِمَآ ءَاتَىٰهُمُ ٱللَّهُ مِن فَضْلِهِۦ هُوَ خَيْرًۭا لَّهُم ۖ بَلْ هُوَ شَرٌّۭ لَّهُمْ ۖ سَيُطَوَّقُونَ مَا بَخِلُوا۟ بِهِۦ يَوْمَ ٱلْقِيَٰمَةِ ۗ وَلِلَّهِ مِيرَٰثُ ٱلسَّمَٰوَٰتِ وَٱلْأَرْضِ ۗ وَٱللَّهُ بِمَا تَعْمَلُونَ خَبِيرٌۭ
And let not those who hoard up that which Allah hath bestowed upon them of His bounty think that it is better for them. Nay, it is worse for them. That which they hoard will be their collar on the Day of Resurrection. Allah's is the heritage of the heavens and the earth, and Allah is Informed of what ye do.
Surah Aal-i-Imraan(3:180)
