6:25
وَمِنۡهُم مَّن یَسۡتَمِعُ إِلَیۡكَۖ وَجَعَلۡنَا عَلَىٰ قُلُوبِهِمۡ أَكِنَّةً أَن یَفۡقَهُوهُ وَفِیۤ ءَاذَانِهِمۡ وَقۡرࣰاۚ وَإِن یَرَوۡا۟ كُلَّ ءَایَةࣲ لَّا یُؤۡمِنُوا۟ بِهَاۖ حَتَّىٰۤ إِذَا جَاۤءُوكَ یُجَـٰدِلُونَكَ یَقُولُ ٱلَّذِینَ كَفَرُوۤا۟ إِنۡ هَـٰذَاۤ إِلَّاۤ أَسَـٰطِیرُ ٱلۡأَوَّلِینَ
Of them are some who listen unto thee, but We have placed upon their hearts veils, lest they should understand, and in their ears a deafness. If they saw every token they would not believe therein; to the point that, when they come unto thee to argue with thee, the disbelievers say: This is naught else than fables of the men of old.
