Al Kahf, 57 Ayah
18:57
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 ٥٧
Wa Man 'Ažlamu Mimman Dhukkira Bi'āyāti Rabbihi Fa'a`rađa `Anhā Wa Nasiya Mā Qaddamat Yadāhu ۚ 'Innā Ja`alnā `Alá Qulūbihim 'Akinnatan 'An Yafqahūhu Wa Fī 'Ādhānihim Waqrāan Wa 'In ۖ Tad`uhum 'Ilá Al-Hudá Falan Yahtadū 'Idhāan 'Abadāan
And who is more unjust than one who is reminded of the verses of his Lord but turns away from them and forgets what his hands have put forth? Indeed, We have placed over their hearts coverings, lest they understand it, and in their ears deafness. And if you invite them to guidance - they will never be guided, then - ever.
