Surah Al-Baqarah (The Cow), Verse 16

اُولٰٓىِٕكَ الَّذِیْنَ اشْتَرَوُا الضَّلٰلَةَ بِالْهُدٰی فَمَا رَبِحَتْ تِّجَارَتُهُمْ وَمَا كَانُوْا مُهْتَدِیْنَ ۟

Ulaaa'ikal lazeenash tara wud dalaalata bilhudaa famaa rabihat tijaaratuhum wa maa kaanoo muhtadeen

“These are they who have bartered Guidance for error: But their traffic is profitless, and they have lost true direction,”

Quran 2:16 (Yusuf Ali Translation)
