18:104
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
It will be those whose effort went astray in the life of the world and who believe nevertheless that they are doing good.
