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
"Those whose efforts have been wasted in this life, while they thought that they were acquiring good by their works?"
