(Al-Kahf) 18 : 104
الَّذِينَ ضَلَّ سَعْيُهُمْ فِي الْحَيَاةِ الدُّنْيَا وَهُمْ يَحْسَبُونَ أَنَّهُمْ يُحْسِنُونَ صُنْعًا
Those whose effort is lost in the worldly life reckon that they are producing well in deeds."
The Arabic Quran reading Fujjar who hide and reject Adhikr prefer a bodily and worldly life than the soul and Hereafter. All their deeds will be futile, and they will get Hell as a fine for their aimless and heedless life here as told in verses 2: 186 and 9: 5. See explanation 2: 12-14; 13: 20-25 and 17: 19.
