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

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

(102) And they belied them (those Ayat) wrongfully and arrogantly, though their ownselves were convinced thereof [i.e. those (Ayat ) are from Allah, and Musa (Moses) is the Messenger of Allah in truth, but they disliked to obey Musa (Moses), and hated to believe in his Message of Monotheism]. So see what was the end of the Mufsidun (disbelievers, disobedient to Allah, evil-doers and liars.).

(103) 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)."

(104) 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.

(105) And We have enjoined on man to be good and dutiful to his parents; but if they strive to make you join with Me (in worship) anything (as a partner) of which you have no knowledge, then obey them not. Unto Me is your return and I shall tell you what you used to do.

(106) But if they (both) strive with you to make you join in worship with Me others that of which you have no knowledge, then obey them not; but behave with them in the world kindly, and follow the path of him who turns to Me in repentance and in obedience. Then to Me will be your return, and I shall tell you what you used to do.

(107) O Prophet (Muhammad صلى الله عليه وسلم)! Keep your duty to Allah, and obey not the disbelievers and the hypocrites (i.e., do not follow their advice). Verily, Allah is Ever All-Knower, All-Wise.

(108) And stay in your houses, and do not display yourselves like that of the times of ignorance, and perform As-Salat (Iqamat-as-Salat), and give Zakat and obey Allah and His Messenger. Allah wishes only to remove Ar-Rijs (evil deeds and sins) from you, O members of the family (of the Prophet صلى الله عليه وسلم), and to purify you with a thorough purification.

(109) 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.

(110) And obey not the disbelievers and the hypocrites, and harm them not (in revenge for their harming you till you are ordered). And put your trust in Allah, and Sufficient is Allah as a Wakil (Trustee, or Disposer of affairs). [Tafsir Al-Qurtubi]
