Al Qalam, 51 Ayah
68:51
وَإِن يَكَادُ ٱلَّذِينَ كَفَرُواْ لَيُزۡلِقُونَكَ بِأَبۡصَٰرِهِمۡ لَمَّا سَمِعُواْ ٱلذِّكۡرَ وَيَقُولُونَ إِنَّهُۥ لَمَجۡنُونٞ ٥١
Wa 'In Yakādu Al-Ladhīna Kafarū Layuzliqūnaka Bi'abşārihim Lammā Sami`ū Adh-Dhikra Wa Yaqūlūna 'Innahu Lamajnūnun
And indeed, those who disbelieve would almost make you slip with their eyes when they hear the message, and they say, "Indeed, he is mad."
