The word(s) "mad" appears 1172 time(s) in 1024 verse(s) in Quran in Mohsin Khan translation.

(321) Say: "O you mankind! Now truth (i.e. the Qur'an and Prophet Muhammad صلى الله عليه وسلم) has come to you from your Lord. So whosoever receives guidance, he does so for the good of his own self; and whosoever goes astray, he does so to his own loss; and I am not (set) over you as a Wakil (disposer of affairs to oblige you for guidance)."

(322) And (O Muhammad صلى الله عليه وسلم), follow the revelation sent unto you, and be patient till Allah gives judgement. And He is the Best of judges.

(323) (Saying) worship none but Allah. Verily, I (Muhammad صلى الله عليه و سلم) am unto you from Him a warner and a bringer of glad tidings.

(324) So perchance you (Muhammad صلى الله عليه و سلم) may give up a part of what is revealed unto you, and that your breast feels straitened for it because they say, "Why has not a treasure been sent down unto him, or an angel has come with him?" But you are only a warner. And Allah is a Wakil (Disposer of affairs, Trustee, Guardian) over all things.

(325) Or they say, "He (Prophet Muhammad صلى الله عليه و سلم) forged it (the Qur'an)." Say: "Bring you then ten forged Surahs (chapters) like unto it, and call whomsoever you can, other than Allah (to your help), if you speak the truth!"

(326) Can they (Muslims) who rely on a clear proof (the Qur'an) from their Lord, and whom a witness [Jibril (Gabriel عليه السلام)] from Him recites (follows) it (can they be equal with the disbelievers); and before it, came the Book of Musa (Moses), a guidance and a mercy, they believe therein, but those of the sects (Jews, Christians and all the other non-Muslim nations) that reject it (the Qur'an), the Fire will be their promised meeting-place. So be not in doubt about it (i.e. those who denied Prophet Muhammad صلى الله عليه و سلم and also denied all that which he brought from Allah. Surely, they will enter Hell). Verily, it is the truth from your Lord, but most of the mankind believe not.

(327) Or they (the pagans of Makkah) say: "He (Muhammad صلى الله عليه و سلم) has fabricated it (the Qur'an)." Say: "If I have fabricated it, upon me be my crimes, but I am innocent of (all) those crimes which you commit."

(328) And it was said: "O earth! Swallow up your water, and O sky! Withhold (your rain)." And the water was made to subside and the Decree (of Allah) was fulfilled (i.e. the destruction of the people of Nuh (Noah). And it (the ship) rested on (Mount) Judi, and it was said: "Away with the people who are Zalimun (polytheists and wrong-doers)!"

(329) This is of the news of the Unseen which We reveal unto you (O Muhammad صلى الله عليه و سلم); neither you nor your people knew it before this. So be patient. Surely, the (good) end is for Al-Muttaqun (the pious - See V.2:2)

(330) "All that we say is that some of our gods (false deities) have seized you with evil (madness)." He said: "I call Allah to witness and bear you witness that I am free from that which you ascribe as partners in worship,
