Surah Al-Baqarah 2:16

أُو۟لَـٰٓئِكَ ٱلَّذِينَ ٱشْتَرَوُا۟ ٱلضَّلَـٰلَةَ بِٱلْهُدَىٰ فَمَا رَبِحَت تِّجَـٰرَتُهُمْ وَمَا كَانُوا۟ مُهْتَدِينَ

Those are the ones who have purchased error [in exchange] for guidance, so their transaction has brought no profit, nor were they guided.

Translation: Saheeh International

Tafsir

Those are they who have bought error for guidance that is they have exchanged the latter for the former; so their commerce has not profited them that is to say they have gained nothing from it indeed they have lost because their destination is the Fire made everlasting for them; nor are they guided in what they did.
