مَثَلُ مَا يُنفِقُونَ فِي هِـذِهِ الْحَيَاةِ الدُّنْيَا كَمَثَلِ رِيحٍ فِيهَا صِرٌّ أَصَابَتْ حَرْثَ قَوْمٍ ظَلَمُواْ أَنفُسَهُمْ فَأَهْلَكَتْهُ وَمَا ظَلَمَهُمُ اللّهُ وَلَـكِنْ أَنفُسَهُمْ يَظْلِمُونَ
The example of what they spend in this worldly life is like that of a wind containing frost which strikes the harvest of a people who have wronged themselves and destroys it. And Allah has not wronged them, but they wrong themselves.
