These are they who have bartered Guidance for error: But their trade is profitless and they have lost true direction, (Surah 2 Verse 16)

Those who conceal Allah's revelations in the Book and purchase for them a miserable profit, they swallow into themselves naught but Fire; Allah will not address them on the Day of Resurrection. Nor purify them: Grievous will be their penalty. (Surah 2, Verse 174)

(In such falsehood) is but a paltry profit; but they will have a most grievous Penalty. (Surah 16, Verse 117)
