18-Surah Al-Kahf ( The Cave ) 57
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.
وَمَنْ أَظْلَمُ مِمَّن ذُكِّرَ بِآيَاتِ رَبِّهِ فَأَعْرَضَ عَنْهَا وَنَسِيَ مَا قَدَّمَتْ يَدَاهُ ۚ إِنَّا جَعَلْنَا عَلَىٰ قُلُوبِهِمْ أَكِنَّةً أَن يَفْقَهُوهُ وَفِي آذَانِهِمْ وَقْرًا ۖ وَإِن تَدْعُهُمْ إِلَى الْهُدَىٰ فَلَن يَهْتَدُوا إِذًا أَبَدًا
Quran's Tafhim ( explanation)
*54) Allah puts a covering over the heart of a person and makes his ears hard of hearing the Truth when he adopts the attitude of contention, dispute, wrangling and argumentation towards the admonition of a well-wisher and tries to defeat the truth with the weapons of falsehood and cunning. Naturally this attitude produces in him obduracy and obstinacy so that he turns a deaf ear towards guidance, and is unwilling to realize his error before seeing his evil end. For such people pay no heed to admonition and warning and insist on falling into the abyss of perdition: then and then alone they are convinced that it was perdition towards which they were rushing headlong.
