البقرة — Al-Baqarah Ayat 16
اُولٰۤىِٕكَ الَّذِيْنَ اشْتَرَوُا الضَّلٰلَةَ بِالْهُدٰىۖ فَمَا رَبِحَتْ تِّجَارَتُهُمْ وَمَا كَانُوْا مُهْتَدِيْنَ
Ulā'ikal-lażīnasytarawuḍ-ḍalālata bil-hudā, famā rabiḥat tijāratuhum wa mā kānū muhtadīn(a).
"Those are the ones who have purchased error [in exchange] for guidance, so their transaction has brought no profit, nor were they guided."
