مَثَلُ مَا يُنفِقُونَ فِى هَٰذِهِ ٱلْحَيَوٰةِ ٱلدُّنْيَا كَمَثَلِ رِيحٍۢ فِيهَا صِرٌّ أَصَابَتْ حَرْثَ قَوْمٍۢ ظَلَمُوٓا۟ أَنفُسَهُمْ فَأَهْلَكَتْهُ ۚ وَمَا ظَلَمَهُمُ ٱللَّهُ وَلَٰكِنْ أَنفُسَهُمْ يَظْلِمُونَ
The likeness of that which they spend in this life of the world is as the likeness of a biting, icy wind which smiteth the harvest of a people who have wronged themselves, and devastateth it. Allah wronged them not, but they do wrong themselves.
