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

(131) This is because they said to those who hate what Allah has sent down: "We will obey you in part of the matter." But Allah knows their secrets.

(132) O you who believe! obey Allah, and obey the Messenger (Muhammad صلى الله عليه وسلم) and render not vain your deeds.

(133) Say (O Muhammad صلى الله عليه وسلم) to the bedouins who lagged behind: "You shall be called to fight against a people given to great warfare, then you shall fight them, or they shall surrender. Then if you obey, Allah will give you a fair reward; but if you turn away as you did turn away before, He will punish you with a painful torment."

(134) No blame or sin is there upon the blind, nor is there blame or sin upon the lame, nor is there blame or sin upon the sick (that they go not for fighting). And whosoever obeys Allah and His Messenger (Muhammad صلى الله عليه وسلم), He will admit him to Gardens beneath which rivers flow (Paradise); and whosoever turns back, He will punish him with a painful torment.

(135) And know that among you there is the Messenger of Allah (صلى الله عليه وسلم). If he were to obey you (i.e. follow your opinions and desires) in much of the matter, you would surely be in trouble. But Allah has endeared the Faith to you and has beautified it in your hearts, and has made disbelief, wickedness and disobedience (to Allah and His Messenger صلى الله عليه وسلم) hateful to you. Such are they who are the rightly guided.

(136) The bedouins say: "We believe." Say: "You believe not but you only say, 'We have surrendered (in Islam),' for Faith has not yet entered your hearts. But if you obey Allah and His Messenger (صلى الله عليه وسلم), He will not decrease anything in reward for your deeds. Verily, Allah is Oft-Forgiving, Most Merciful."

(137) (It will be said): "This is what you were promised - (it is) for those oft-returning (to Allah) in sincere repentance, and those who preserve their covenant with Allah (by obeying Him in all what He has ordered, and worshipping none but Allah Alone, i.e. follow Allah's religion - Islamic Monotheism).

(138) And the people of Nuh (Noah) aforetime. Verily, they were more unjust and more rebellious and transgressing [in disobeying Allah and His Messenger Nuh (Noah) عليه السلام].

(139) As a Favour from Us. Thus do We reward him who gives thanks (by obeying Us).

(140) Are you afraid of spending in charity before your private consultation (with him)? If then you do it not, and Allah has forgiven you, then (at least) perform Salat (Iqamat-as-Salat ) and give Zakat and obey Allah (i.e. do all that Allah and His Messenger صلى الله عليه وسلم order you to do). And Allah is All-Aware of what you do.
