Quran 18:57 from Surah Al-Kahf on Divine Marvels.
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
English translation: And who (is) more wrong than (he) who is reminded of the Verses (of) his Lord but turns away from them and forgets what have sent forth his hands Indeed We [We] have placed over their hearts coverings lest they understand it and in their ears (is) deafness And if you call them to the guidance then never they will be guided then ever
Transliteration: waman azlamu mimman dhukkira biayati rabbihi fa-a'rada anha wanasiya ma qaddamat yadahu inna ja'alna ala qulubihim akinnatan an yafqahuhu wafi adhanihim waqran wa-in tad'uhum ila al-huda falan yahtadu idhan abadan
