بِسْمِ اللهِ الرَّحْمانِ الرَّحِيمِ

In the name of Allah, the Entirely Merciful, the Especially Merciful.

قُلْ هَلْ نُنَبِّئُكُم بِالأخْسَرِينَ أَعْمَالاً

 Say, [O Muhammad], "Shall we [believers] inform you of the greatest losers as to [their] deeds?

الَّذِينَ ضَلَّ سَعْيُهُمْ في الْحَياةِ الدُّنْيَا وَهُمْ يَحْسَبُونَ أَنَّهُمْ يُحْسِنُونَ صُنْعًا

 [They are] those whose effort is lost in worldly life, while they think that they are doing well in work."
