Sura: AL‑QALAM 

Aya : 51

وَإِن يَكَادُ ٱلَّذِينَ كَفَرُواْ لَيُزۡلِقُونَكَ بِأَبۡصَٰرِهِمۡ لَمَّا سَمِعُواْ ٱلذِّكۡرَ وَيَقُولُونَ إِنَّهُۥ لَمَجۡنُونٞ

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."
