The Holy Quran 18:104 — Surah Al-Kahf

Arabic text

ٱلَّذِينَ ضَلَّ سَعْيُهُمْ فِى ٱلْحَيَوٰةِ ٱلدُّنْيَا وَهُمْ يَحْسَبُونَ أَنَّهُمْ يُحْسِنُونَ صُنْعًا

Translation

They are those whose efforts (good acts) are destroyed in this worldly life (not accepted by Allaah because they do not have Imaan or because their intentions are incorrect) while they think that they are (definitely) carrying out good acts (and that they will be rewarded).

Tafsir (excerpt) — Tafsir Usmani

The greatest losers are the seekers of this world: that is, on the Day of Resurrection the greatest losers will be those whose every effort was for this world. The thought of the Hereafter never occurred to them; they kept regarding worldly progress and material success alone as the highest summit (this is how it is understood from Mudih al-Quran).
