The word(s) "madman" appears 8 time(s) in 8 verse(s) in Quran in Mohsin Khan translation.

(1) [Fir'aun (Pharaoh)] said: "Verily, your Messenger who has been sent to you is a madman!"

(2) Then they had turned away from him (Messenger Muhammad صلى الله عليه و سلم) and said: (He is) one taught (by a human being), a madman!"

(3) But [Fir'aun (Pharaoh)] turned away (from Belief in might) along with his hosts, and said: "A sorcerer, or a madman."

(4) Likewise, no Messenger came to those before them but they said: "A sorcerer or a madman!"

(5) Therefore, remind (mankind of Islamic Monotheism, O Muhammad صلى الله عليه وسلم). By the Grace of Allah, you are neither a soothsayer, nor a madman.

(6) The people of Nuh (Noah) denied (their Messenger) before them. They rejected Our slave, and said: "A madman!" and he was insolently rebuked and threatened.

(7) And verily, those who disbelieve would almost make you slip with their eyes (through hatred) when they hear the Reminder (the Qur'an), and they say: "Verily, he (Muhammad صلى الله عليه وسلم) is a madman!"

(8) And (O people) your companion (Muhammad صلى الله عليه وسلم) is not a madman.
