Al-Hijr - 15:6

وَقَالُواْ يَا أَيُّهَا الَّذِي نُزِّلَ عَلَيْهِ الذِّكْرُ إِنَّكَ لَمَجْنُونٌ
[15:6]
And they say: O you to whom the Reminder has been revealed! you are most surely insane:
They say: "O thou to whom the Message is being revealed! truly thou art mad (or possessed)!
And they say: O thou unto whom the Reminder is revealed, lo! thou art indeed a madman!
