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

(281) He is only a man in whom is a madness, so watch him for a while.

(282) And the chieftains of his folk, who disbelieved and denied the meeting of the Hereafter, and whom We had made soft in the life of the world, said: This is only a mortal like you, who eateth of that whereof ye eat and drinketh of that ye drink.

(283) So the (Awful) Cry overtook them rightfully, and We made them like as wreckage (that a torrent hurleth). A far removal for wrongdoing folk!

(284) Then We sent our messengers one after another. Whenever its messenger came unto a nation they denied him; so We caused them to follow one another (to disaster) and We made them bywords. A far removal for folk who believe not!

(285) And We made the son of Mary and his mother a portent, and We gave them refuge on a height, a place of flocks and watersprings.

(286) Or say they: There is a madness in him? Nay, but he bringeth them the Truth; and most of them are haters of the Truth.

(287) Or dost thou ask of them (O Muhammad) any tribute? But the bounty of thy Lord is better, for He is Best of all who make provision.

(288) And (O Muhammad) say: My Lord! Forgive and have mercy, for Thou art Best of all who show mercy.

(289) Say (unto them, O Muhammad): He who knoweth the secret of the heavens and the earth hath revealed it. Lo! He ever is Forgiving, Merciful.

(290) And Noah's folk, when they denied the messengers, We drowned them and made of them a portent for mankind. We have prepared a painful doom for evil-doers.
