وَمَنۡ أَظۡلَمُ مِمَّن ذُكِّرَ بِـَٔايَٰتِ رَبِّهِۦ فَأَعۡرَضَ عَنۡهَا وَنَسِيَ مَا قَدَّمَتۡ يَدَاهُۚ إِنَّا جَعَلۡنَا عَلَىٰ قُلُوبِهِمۡ أَكِنَّةً أَن يَفۡقَهُوهُ وَفِيٓ ءَاذَانِهِمۡ وَقۡرٗاۖ وَإِن تَدۡعُهُمۡ إِلَى ٱلۡهُدَىٰ فَلَن يَهۡتَدُوٓاْ إِذًا أَبَدٗا

Wa man azlamu mimman zukkira bi ayaati Rabbihee fa-a'rada 'anhaa wa nasiya maa qaddamat yadaah; innaa ja'alnaa 'alaa quloobihim akinnatan any yafqahoohu wa feee aazaanihim waqraa; wa in tad'uhum ilal hudaa falany yahtadooo izan abadaa

And who doth more wrong than one who is reminded of the Signs of his Lord, but turns away from them, forgetting the (deeds) which his hands have sent forth? Verily We have set veils over their hearts lest they should understand this, and over their ears, deafness, if thou callest them to guidance, even then will they never accept guidance.

— Al-Kahf (ٱلْكَهْف), 18:57
