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

(811) And those who disbelieve (the strong and wealthy) say of those who believe (the weak and poor): "Had it (Islamic Monotheism to which Muhammad صلى الله عليه وسلم is inviting mankind) been a good thing, they (the weak and poor) would not have preceded us thereto!" And when they have not let themselves be guided by it (this Qur'an), they say: "This is an ancient lie!"

(812) And (remember) when We sent towards you (Muhammad صلى الله عليه وسلم) a group (three to ten persons) of the jinn, (quietly) listening to the Qur'an. When they stood in the presence thereof, they said: "Listen in silence!" And when it was finished, they returned to their people, as warners.

(813) O our people! Respond (with obedience) to Allah's Caller (i.e. Allah's Messenger Muhammad صلى الله عليه وسلم), and believe in him (i.e. believe in that which Muhammad صلى الله عليه وسلم has brought from Allah and follow him). He (Allah) will forgive you of your sins, and will save you from a painful torment (i.e. Hell-fire)

(814) Therefore be patient (O Muhammad صلى الله عليه وسلم) as did the Messengers of strong will and be in no haste about them (disbelievers). On the Day when they will see that (torment) with which they are promised (i.e. threatened, it will be) as if they had not stayed more than an hour in a single day. (O mankind! this Qur'an is sufficient as) a clear Message (or proclamation to save yourself from destruction). But shall any be destroyed except the people who are Al-Fasiqun (the rebellious against Allah's Command, the disobedient to Allah)?

(815) Those who disbelieve (in the Oneness of Allah, and in the Message of Prophet Muhammad صلى الله عليه وسلم), and hinder (men) from the Path of Allah (Islamic Monotheism), He will render their deeds vain.

(816) But those who believe and do righteous good deeds, and believe in that which is sent down to Muhammad (صلى الله عليه وسلم) - for it is the truth from their Lord - He will expiate from them their sins, and will make good their state.

(817) And admit them to Paradise which He has made known to them (i.e. they will know their places in Paradise better than they used to know their homes in the world). [Tafsir Ibn Kathir ]

(818) That is because they hate that which Allah has sent down (this Qur'an and Islamic laws, etc.); so He has made their deeds fruitless.

(819) And many a town, stronger than your town (Makkah) (O Muhammad صلى الله عليه وسلم) which has driven you out We have destroyed. And there was none to help them.

(820) And among them are some who listen to you (O Muhammad صلى الله عليه وسلم) till when they go out from you, they say to those who have received knowledge: "What has he said just now? Such are men whose hearts Allah has sealed, and they follow their lusts (evil desires).
