ٱلَّذِينَ ضَلَّ سَعْيُهُمْ فِى ٱلْحَيَوٰةِ ٱلدُّنْيَا وَهُمْ يَحْسَبُونَ أَنَّهُمْ يُحْسِنُونَ صُنْعًا
Allazeena dalla sa'yuhum fil hayaatid dunyaa wa hum yahsaboona annahum yuhsinoona sun'aa
those whose striving in the life of this world has gone astray, while they suppose they are doing good work.
