The word(s) "mad" appears 583 time(s) in 554 verse(s) in Quran in Muhammad Pickthal translation.

(341) Muhammad is not the father of any man among you, but he is the messenger of Allah and the Seal of the Prophets; and Allah is ever Aware of all things.

(342) O Prophet! Lo! We have made lawful unto thee thy wives unto whom thou hast paid their dowries, and those whom thy right hand possesseth of those whom Allah hath given thee as spoils of war, and the daughters of thine uncle on the father's side and the daughters of thine aunts on the father's side, and the daughters of thine uncle on the mother's side and the daughters of thine aunts on the mother's side who emigrated with thee, and a believing woman if she give herself unto the Prophet and the Prophet desire to ask her in marriage - a privilege for thee only, not for the (rest of) believers - We are Aware of that which We enjoined upon them concerning their wives and those whom their right hands possess - that thou mayst be free from blame, for Allah is ever Forgiving, Merciful.

(343) Hath he invented a lie concerning Allah, or is there in him a madness? Nay, but those who disbelieve in the Hereafter are in torment and far error.

(344) And assuredly We gave David grace from Us, (saying): O ye hills and birds, echo his psalms of praise! And We made the iron supple unto him,

(345) They made for him what he willed: synagogues and statues, basins like wells and boilers built into the ground. Give thanks, O House of David! Few of My bondmen are thankful.

(346) And We set, between them and the towns which We had blessed, towns easy to be seen, and We made the stage between them easy, (saying): Travel in them safely both by night and day.

(347) But they said: Our Lord! Make the stage between our journeys longer. And they wronged themselves, therefore We made them bywords (in the land) and scattered them abroad, a total scattering. Lo! herein verily are portents for each steadfast, grateful (heart).

(348) And he had no warrant whatsoever against them, save that We would know him who believeth in the Hereafter from him who is in doubt thereof; and thy Lord (O Muhammad) taketh note of all things.

(349) Say (O Muhammad): Call upon those whom ye set up beside Allah! They possess not an atom's weight either in the heavens or in the earth, nor have they any share in either, nor hath He an auxiliary among them.

(350) And We have not sent thee (O Muhammad) save as a bringer of good tidings and a warner unto all mankind; but most of mankind know not.
