Al-Baqarah 2:15

أَلَا إِنَّهُمْ هُمُ الْمُفْسِدُونَ وَلَـٰكِن لَّا يَشْعُرُونَ

Unquestionably, it is they who are the corrupters, but they perceive [it] not.

وَإِذَا قِيلَ لَهُمْ آمِنُوا كَمَا آمَنَ النَّاسُ قَالُوا أَنُؤْمِنُ كَمَا آمَنَ السُّفَهَاءُ ۗ أَلَا إِنَّهُمْ هُمُ السُّفَهَاءُ وَلَـٰكِن لَّا يَعْلَمُونَ

And when it is said to them, "Believe as the people have believed," they say, "Should we believe as the foolish have believed?" Unquestionably, it is they who are the foolish, but they know [it] not.

وَإِذَا لَقُوا الَّذِينَ آمَنُوا قَالُوا آمَنَّا وَإِذَا خَلَوْا إِلَىٰ شَيَاطِينِهِمْ قَالُوا إِنَّا مَعَكُمْ إِنَّمَا نَحْنُ مُسْتَهْزِئُونَ

And when they meet those who believe, they say, "We believe"; but when they are alone with their evil ones, they say, "Indeed, we are with you; we were only mockers."

أُولَـٰئِكَ الَّذِينَ اشْتَرَوُا الضَّلَالَةَ بِالْهُدَىٰ فَمَا رَبِحَت تِّجَارَتُهُمْ وَمَا كَانُوا مُهْتَدِينَ

Those are the ones who have purchased error [in exchange] for guidance, so their transaction has brought no profit, nor were they guided.

مَثَلُهُمْ كَمَثَلِ الَّذِي اسْتَوْقَدَ نَارًا فَلَمَّا أَضَاءَتْ مَا حَوْلَهُ ذَهَبَ اللَّهُ بِنُورِهِمْ وَتَرَكَهُمْ فِي ظُلُمَاتٍ لَّا يُبْصِرُونَ

Their example is that of one who kindled a fire, but when it illuminated what was around him, Allah took away their light and left them in darkness [so] they could not see.

صُمٌّ بُكْمٌ عُمْيٌ فَهُمْ لَا يَرْجِعُونَ

Deaf, dumb and blind - so they will not return [to the right path].
