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

(121) Say (O Muhammad صلى الله عليه وسلم): "Verily I am commanded to worship Allah (Alone) by obeying Him and doing religious deeds sincerely for His sake only.

(122) Say (O Muhammad صلى الله عليه وسلم): "Verily if I disobey my Lord, I am afraid of the torment of a great Day."

(123) And when Allah Alone is mentioned, the hearts of those who believe not in the Hereafter are filled with disgust (from the Oneness of Allah توحيد الله) and when those (whom they obey or worship) besides Him [like all false deities other than Allah, - it may be a Messenger, an angel, a pious man, a jinni, or any other creature even idols, graves of religious people, saints, priests, monks and others.] are mentioned, behold, they rejoice!

(124) It is He Who shows you His Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) and sends down (rain with which grows) provision for you from the sky. And none remembers but those who turn (to Allah in obedience and) in repentance (by begging His Pardon and by worshipping and obeying Him Alone and none else).

(125) Verily those who dispute about the Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) of Allah, without any authority having come to them, there is nothing else in their breasts except pride [to accept you (Muhammad صلى الله عليه وسلم) as a Messenger of Allah and to obey you] . They will never have it (i.e. Prophethood which Allah has bestowed upon you). So seek refuge in Allah (O Muhammad صلى الله عليه وسلم from the arrogants). Verily, it is He Who is the All-Hearer, the All-Seer.

(126) Thus he [Fir'aun (Pharaoh)] befooled (and misled) his people, and they obeyed him. Verily, they were ever a people who were Fasiqun (rebellious, disobedient to Allah).

(127) And when 'Îsa (Jesus) came with (Our) clear Proofs, he said: "I have come to you with Al-Hikmah (Prophethood), and in order to make clear to you some of the (points) in which you differ. Therefore fear Allah and obey me.

(128) And those whom they invoke instead of Him have no power of intercession - except for those who bear witness to the truth knowingly (i.e. believed in the Oneness of Allah, and obeyed His Orders), and they know (the facts about the Oneness of Allah).

(129) On the Day when those who disbelieve (in the Oneness of Allah - Islamic Monotheism) will be exposed to the Fire (it will be said): "You received your good things in the life of the world, and you took your pleasure therein. Now this Day you shall be recompensed with a torment of humiliation, because you were arrogant in the land without a right, and because you used to rebel against Allah's Command (disobey Allah).

(130) Those who believe say: "Why is not a Surah (chapter of the Qur'an) sent down (for us)? But when a decisive Surah (explaining and ordering things) is sent down, and fighting (Jihad - holy fighting in Allah's cause) is mentioned (i.e. ordained) therein, you will see those in whose hearts is a disease (of hypocrisy) looking at you with a look of one fainting to death. But it was better for them (hypocrites, to listen to Allah and to obey Him).
