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

(521) And strive hard in Allah's Cause as you ought to strive (with sincerity and with all your efforts that His Name should be superior). He has chosen you (to convey His Message of Islamic Monotheism to mankind by inviting them to His religion of Islam), and has not laid upon you in religion any hardship: it is the religion of your father Ibrahim (Abraham) (Islamic Monotheism). It is He (Allah) Who has named you Muslims both before and in this (the Qur'an), that the Messenger (Muhammad صلى الله عليه وسلم) may be a witness over you and you be witnesses over mankind! So perform As-Salat (Iqamat-as-Salat), give Zakat and hold fast to Allah [i.e. have confidence in Allah, and depend upon Him in all your affairs]. He is your Maula (Patron, Lord), what an Excellent Maula (Patron, Lord) and what an Excellent Helper!

(522) Thereafter We made him (the offspring of Adam) as a Nutfah (mixed drops of the male and female sexual discharge and lodged it) in a safe lodging (womb of the woman).

(523) Then We made the Nutfah into a clot (a piece of thick coagulated blood), then We made the clot into a little lump of flesh, then We made out of that little lump of flesh bones, then We clothed the bones with flesh, and then We brought it forth as another creation. So Blessed is Allah, the Best of creators.

(524) "He is only a man in whom is madness, so wait for him a while."

(525) So As-Saihah (torment - awful cry) overtook them in truth (with justice), and We made them as rubbish of dead plants. So away with the people who are Zalimun (polytheists, wrong-doers, disbelievers in the Oneness of Allah, disobedient to His Messengers).

(526) Then We sent Our Messengers in succession. Every time there came to a nation their Messenger, they denied him; so We made them follow one another (to destruction), and We made them as Ahadith (the true stories for mankind to learn a lesson from them). So away with a people who believe not!

(527) And We made the son of Maryam (Mary) and his mother as a sign, and We gave them refuge on high ground, a place of rest, security and flowing streams.

(528) O (you) Messengers! Eat of the Tayyibat [all kinds of Halal foods which Allah has made lawful (meat of slaughtered eatable animals, milk products, fats, vegetables, fruits, etc.] and do righteous deeds. Verily! I am Well-Acquainted with what you do.

(529) Or is it that they did not recognize their Messenger (Muhammad صلى الله عليه وسلم) so they deny him?

(530) Or say they: There is madness in him? Nay, but he brought them the truth [i.e. Tauhid: Worshipping Allah Alone in all aspects, the Qur'an and the religion of Islam], but most of them (the disbelievers) are averse to the truth.
