Disbelief and Hostility toward Divine Revelation

وَإِن يَكَادُ ٱلَّذِينَ كَفَرُوا۟ لَيُزْلِقُونَكَ بِأَبْصَـٰرِهِمْ لَمَّا سَمِعُوا۟ ٱلذِّكْرَ وَيَقُولُونَ إِنَّهُۥ لَمَجْنُونٌ

And indeed, those who disbelieve would almost make you slip with their eyes [i.e., looks] when they hear the message, and they say, "Indeed, he is mad."
