(Al-Muaminoon) 23 : 103
وَمَنْ خَفَّتْ مَوَازِينُهُ فَأُولَٰئِكَ الَّذِينَ خَسِرُوا أَنْفُسَهُمْ فِي جَهَنَّمَ خَالِدُونَ
And the one who made his balance light, they are those who have lost their soul, they will be in Hell forever.
The Arabic Quran reading Fujjar who hide and reject Adhikr are the greatest losers of deeds whose effort is lost in the worldly life while they reckon that they are producing well in deeds as explained in verses 18: 103-106. Their prayers will not be responded and their deeds such as fasting, charity, and pilgrimage will not be accepted; instead, they will get Hell as a fine for their aimless and heedless life as explained in verses 7: 179 and 15: 44. See explanation 2: 186 and 20: 124-127.
