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

(671) And those who disbelieve say: "We believe not in this Qur'an nor in that which was before it." But if you could see when the Zalimun (polytheists and wrong-doers) will be made to stand before their Lord, how they will cast the (blaming) word one to another! Those who were deemed weak will say to those who were arrogant: "Had it not been for you, we should certainly have been believers!"

(672) Say (O Muhammad صلى الله عليه وسلم): "Verily, my Lord enlarges the provision to whom He wills and restricts, but most men know not."

(673) And when Our Clear Verses are recited to them, they say: "This (Muhammad صلى الله عليه وسلم) is naught but a man who wishes to hinder you from that which your fathers used to worship." And they say: "This (the Qur'an) is nothing but an invented lie." And those who disbelieve say of the truth when it has come to them (i.e. Prophet Muhammad صلى الله عليه وسلم when Allah sent him as a Messenger with proofs, evidence, verses of this Qur'an, lessons, signs, etc.): "This is nothing but evident magic!"

(674) And We had not given them Scriptures which they could study, nor sent to them before you (O Muhammad صلى الله عليه وسلم) any warner (Messenger).

(675) Say (to them O Muhammad صلى الله عليه وسلم): "I exhort you to one (thing) only: that you stand up for Allah's sake in pairs and singly, and reflect (within yourselves the life history of the Prophet صلى الله عليه وسلم): there is no madness in your companion (Muhammad صلى الله عليه وسلم). He is only a warner to you in face of a severe torment."

(676) Say (O Muhammad صلى الله عليه وسلم): "Whatever wage I might have asked of you is yours. My wage is from Allah only, and He is a Witness over all things."

(677) Say (O Muhammad صلى الله عليه وسلم): "Verily my Lord sends down (Revelation and makes apparent) the truth (i.e. this Revelation that had come to me), the All-Knower of the Ghaib (Unseen).

(678) Say (O Muhammad صلى الله عليه وسلم): "Al-Haqq (the truth i.e. the Qur'an and Allah's Revelation) has come, and Al-Batil [falsehood - Iblis (Satan)] can neither create anything nor resurrect (anything)."

(679) Indeed they did disbelieve (in the Oneness of Allah, Islam, the Qur'an and Muhammad صلى الله عليه وسلم) before (in this world), and they (used to) conjecture about the Unseen [i.e. the Hereafter, Hell, Paradise, Resurrection and the Promise of Allah (by saying) all that is untrue], from a far place.

(680) All the praises and thanks be to Allah, the (only) Originator [or the (Only) Creator] of the heavens and the earth, Who made the angels messengers with wings, two or three or four. He increases in creation what He wills. Verily, Allah is Able to do all things.
