Al-Baqarah - 2:16

أُوْلَـئِكَ الَّذِينَ اشْتَرُوُاْ الضَّلاَلَةَ بِالْهُدَى فَمَا رَبِحَت تِّجَارَتُهُمْ وَمَا كَانُواْ مُهْتَدِينَ
[2:16]
These are they who buy error for the right direction, so their bargain shall bring no gain, nor are they the followers of the right direction.
These are they who have bartered Guidance for error: But their traffic is profitless, and they have lost true direction,
These are they who purchase error at the price of guidance, so their commerce doth not prosper, neither are they guided.
