trading falsehood for truth

أُو۟لَـٰٓئِكَ ٱلَّذِينَ ٱشْتَرَوُا۟ ٱلضَّلَـٰلَةَ بِٱلْهُدَىٰ وَٱلْعَذَابَ بِٱلْمَغْفِرَةِ ۚ فَمَآ أَصْبَرَهُمْ عَلَى ٱلنَّارِ

Those are the ones who have exchanged guidance for error and forgiveness for punishment. How patient they are for [i.e., in pursuit of] the Fire!
