Surah Al-Kahf · سُوْرَةُ الْكَهْفِ · Juz 15
Q 18:57
وَمَنْ أَظْلَمُ مِمَّن ذُكِّرَ بِـَٔايَـٰتِ رَبِّهِۦ فَأَعْرَضَ عَنْهَا وَنَسِىَ مَا قَدَّمَتْ يَدَاهُ ۚ إِنَّا جَعَلْنَا عَلَىٰ قُلُوبِهِمْ أَكِنَّةً أَن يَفْقَهُوهُ وَفِىٓ ءَاذَانِهِمْ وَقْرًا ۖ وَإِن تَدْعُهُمْ إِلَى ٱلْهُدَىٰ فَلَن يَهْتَدُوٓا۟ إِذًا أَبَدًا
Translations
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.Quel pire injuste que celui à qui on a rappelé les versets de son Seigneur et qui en détourna le dos en oubliant ce que ses deux mains ont commis? Nous avons placé des voiles sur leurs cœurs, de sorte qu'ils ne comprennent pas (le Coran), et mis une lourdeur dans leurs oreilles. Même si tu les appelles vers la bonne voie, jamais ils ne pourront donc se guider.Tafsir
There is no one more oppressive that the person who was reminded of the verses of his Lord, but he did not pay any attention to the threat of punishment contained therein and he turned away from taking a lesson, forgetting the disbelief and sins he had done in his worldly life without repenting. I have placed on the hearts of people with this description covers that prevent them from understanding the Qur’ān, and in their ears deafness so that they cannot listen to it acceptingly. If you call them to faith they will never respond to what you call them towards as long as there are covers on their hearts and deafness in their ears.
