Surah Al-Qalam (The Pen), Verse 51

وَاِنْ یَّكَادُ الَّذِیْنَ كَفَرُوْا لَیُزْلِقُوْنَكَ بِاَبْصَارِهِمْ لَمَّا سَمِعُوا الذِّكْرَ وَیَقُوْلُوْنَ اِنَّهٗ لَمَجْنُوْنٌ ۟

Wa iny-yakaadul lazeena kafaroo la-yuzliqoonaka biabsaarihim lammaa sami'uz-Zikra wa yaqooloona innahoo lamajnoon

“And the Unbelievers would almost trip thee up with their eyes when they hear the Message; and they say: "Surely he is possessed!"”
