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

Some of them listen to you, but We placed veils over their hearts, preventing them from understanding it, and deafness in their ears. Even if they witnessed every sign, they wouldn’t believe in it. When they come to argue with you, the disbelievers say, “This is nothing but legends of the ancients.”
