Surat Al-Qalam (The Pen) - القلم

وَإِن يَكَادُ ٱلَّذِينَ كَفَرُوا۟ لَيُزْلِقُونَكَ بِأَبْصَٰرِهِمْ لَمَّا سَمِعُوا۟ ٱلذِّكْرَ وَيَقُولُونَ إِنَّهُۥ لَمَجْنُونٌ ﴿٥١﴾ وَمَا هُوَ إِلَّا ذِكْرٌ لِّلْعَٰلَمِينَ﴿٥٢﴾

And those who disbelieve would almost smite you with their eyes when they hear the reminder, and they say: Most surely he is mad. And it is naught but a reminder to the nations.
