Quran 18:103 — The Cave (Al-Kahf)

Say, "Shall I tell you who the worst losers are?

[18:102] Do those who disbelieve think that they can get away with setting up My servants as gods beside Me? We have prepared for the disbelievers Hell as an eternal abode.

[18:104] "They are the ones whose works in this life are totally astray, but they think that they are doing good."
