فَأَرْسَلْنَا عَلَيْهِمْ رِيحًۭا صَرْصَرًۭا فِىٓ أَيَّامٍۢ نَّحِسَاتٍۢ لِّنُذِيقَهُمْ عَذَابَ ٱلْخِزْىِ فِى ٱلْحَيَوٰةِ ٱلدُّنْيَا ۖ وَلَعَذَابُ ٱلْءَاخِرَةِ أَخْزَىٰ ۖ وَهُمْ لَا يُنصَرُونَ
Therefor We let loose on them a raging wind in evil days, that We might make them taste the torment of disgrace in the life of the world. And verily the doom of the Hereafter will be more shameful, and they will not be helped.
