The word(s) "obey" appears 176 time(s) in 164 verse(s) in Quran in Mohsin Khan translation.

(31) And remember Allah's Favour to you and His Covenant with which He bound you when you said: "We hear and we obey." And fear Allah. Verily, Allah is All-Knower of that which is in (the secrets of your) breasts.

(32) And from those who call themselves Christians, We took their covenant, but they have abandoned a good part of the Message that was sent to them. So We planted amongst them enmity and hatred till the Day of Resurrection (when they discarded Allah's Book, disobeyed Allah's Messengers and His Orders and transgressed beyond bounds in Allah's disobedience); and Allah will inform them of what they used to do.

(33) But whosoever repents after his crime and does righteous good deeds (by obeying Allah), then verily, Allah will pardon him (accept his repentance). Verily, Allah is Oft-Forgiving, Most Merciful.

(34) Those among the Children of Israel who disbelieved were cursed by the tongue of Dawud (David) and 'Îsa (Jesus), son of Maryam (Mary). That was because they disobeyed (Allah and the Messengers) and were ever transgressing beyond bounds.

(35) And obey Allah and the Messenger (Muhammad صلى الله عليه وسلم), and beware (of even coming near to drinking or gambling or Al-Ansab, or Al-Azlam, etc.) and fear Allah. Then if you turn away, you should know that it is Our Messenger's duty to convey (the Message) in the clearest way.

(36) Say: "I fear, if I disobey my Lord, the torment of a Mighty Day."

(37) When those who believe in Our Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) come to you, say: "Salamun 'Alaikum" (peace be on you); your Lord has written (prescribed) Mercy for Himself, so that if any of you does evil in ignorance, and thereafter repents and does righteous good deeds (by obeying Allah), then surely, He is Oft-Forgiving, Most Merciful.

(38) And if you obey most of those on the earth, they will mislead you far away from Allah's Path. They follow nothing but conjectures, and they do nothing but lie.

(39) Eat not (O believers) of that (meat) on which Allah's Name has not been pronounced (at the time of the slaughtering of the animal), for sure it is Fisq (a sin and disobedience of Allah). And certainly, the Shayatin (devils) do inspire their friends (from mankind) to dispute with you, and if you obey them [by making Al-Maitah (a dead animal) legal by eating it], then you would indeed be Mushrikun (polytheists); [because they (devils and their friends) made lawful to you to eat that which Allah has made unlawful to eat and you obeyed them by considering it lawful to eat, and by doing so you worshipped them; and to worship others besides Allah is polytheism].

(40) And this is a blessed Book (the Qur'an) which We have sent down, so follow it and fear Allah (i.e. do not disobey His Orders), that you may receive mercy (i.e. be saved from the torment of Hell).
