Surah Al-Baqarah (البقرة) Ayah 16 - Tafsir

أُو۟لَٰٓئِكَ ٱلَّذِينَ ٱشْتَرَوُا۟ ٱلضَّلَٰلَةَ بِٱلْهُدَىٰ فَمَا رَبِحَت تِّجَٰرَتُهُمْ 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."
