وَمِنهُم مَن يَستَمِعُ إِلَيكَ ۖ وَجَعَلنا عَلىٰ قُلوبِهِم أَكِنَّةً أَن يَفقَهوهُ وَفي آذانِهِم وَقرًا ۚ وَإِن يَرَوا كُلَّ آيَةٍ لا يُؤمِنوا بِها ۚ حَتّىٰ إِذا جاءوكَ يُجادِلونَكَ يَقولُ الَّذينَ كَفَروا إِن هـٰذا إِلّا أَساطيرُ الأَوَّلينَ

And among them are those who listen to you, but We have placed over their hearts coverings, lest they understand it, and in their ears deafness. And if they should see every sign, they will not believe in it. Even when they come to you arguing with you, those who disbelieve say, "This is not but legends of the former peoples."
