The word(s) "disobey" appears 54 time(s) in 53 verse(s) in Quran in Mohsin Khan translation.

(31) Then they both ate of the tree, and so their private parts became manifest to them, and they began to cover themselves with the leaves of the Paradise for their covering. Thus did Adam disobey his Lord, so he went astray.

(32) And thus do We requite him who transgresses beyond bounds [i.e. commits the great sins and disobeys his Lord (Allah) and believes not in His Messengers, and His revealed Books, like this Qur'an], and believes not in the Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) of his Lord; and the torment of the Hereafter is far more severe and more lasting.

(33) Truly, Allah defends those who believe. Verily, Allah likes not any treacherous ingrate to Allah [those who disobey Allah but obey Shaitan (Satan)].

(34) To Fir'aun (Pharaoh) and his chiefs, but they behaved insolently and they were people self-exalting (by disobeying their Lord, and exalting themselves over and above the Messenger of Allah).

(35) Then if they disobey you, say: "I am innocent of what you do."

(36) Say to them (O Muhammad صلى الله عليه وسلم) "Travel in the land and see how has been the end of the Mujrimun (criminals, those who denied Allah's Messengers and disobeyed Allah)."

(37) And how many a town (population) have We destroyed, which was thankless for its means of livelihood (disobeyed Allah, and His Messengers, by doing evil deeds and crimes)! And those are their dwellings, which have not been inhabited after them except a little. And verily! We have been the inheritors.

(38) It is not for a believer, man or woman, when Allah and His Messenger have decreed a matter that they should have any option in their decision. And whoever disobeys Allah and His Messenger, he has indeed strayed into a plain error.

(39) Those who were deemed weak will say to those who were arrogant: "Nay, but it was your plotting by night and day: when you ordered us to disbelieve in Allah and set up rivals to Him!" And each of them (parties) will conceal their own regrets (for disobeying Allah during this worldly life), when they behold the torment. And We shall put iron collars round the necks of those who disbelieved. Are they requited aught except what they used to do?

(40) They (Messengers) said: "Your evil omens be with you! (Do you call it "evil omen") because you are admonished? Nay, but you are a people Musrifun (transgressing all bounds by committing all kinds of great sins, and by disobeying Allah).
