68:51 وَإِن يَكَادُ ٱلَّذِينَ كَفَرُوا۟ لَيُزْلِقُونَكَ بِأَبْصَٰرِهِمْ لَمَّا سَمِعُوا۟ ٱلذِّكْرَ وَيَقُولُونَ إِنَّهُۥ لَمَجْنُونٌ
And those who disbelieve would almost smite you with their eyes when they hear the reminder, and they say: Most surely he is mad. Those who disbelieved show their ridicule in their eyes when they hear the message and say, "He is crazy!"
