The word(s) "obey" appears 89 time(s) in 80 verse(s) in Quran in Abdullah Yusuf Ali translation.

(11) On that day those who reject Faith and disobey the messenger will wish that the earth Were made one with them: But never will they hide a single fact from Allah!

(12) Of the Jews there are those who displace words from their (right) places, and say: "We hear and we disobey"; and "Hear what is not Heard"; and "Ra'ina"; with a twist of their tongues and a slander to Faith. If only they had said: "What hear and we obey"; and "Do hear"; and "Do look at us"; it would have been better for them, and more proper; but Allah hath cursed them for their Unbelief; and but few of them will believe.

(13) O ye who believe! obey Allah, and obey the Messenger, and those charged with authority among you. If ye differ in anything among yourselves, refer it to Allah and His Messenger, if ye do believe in Allah and the Last Day: That is best, and most suitable for final determination.

(14) We sent not a messenger, but to be obeyed, in accordance with the will of Allah. If they had only, when they were unjust to themselves, come unto thee and asked Allah's forgiveness, and the Messenger had asked forgiveness for them, they would have found Allah indeed Oft-returning, Most Merciful.

(15) All who obey Allah and the messenger are in the company of those on whom is the Grace of Allah,- of the prophets (who teach), the sincere (lovers of Truth), the witnesses (who testify), and the Righteous (who do good): Ah! what a beautiful fellowship!

(16) He who obeys the Messenger, obeys Allah: But if any turn away, We have not sent thee to watch over their (evil deeds).

(17) And call in remembrance the favour of Allah unto you, and His covenant, which He ratified with you, when ye said: "We hear and we obey": And fear Allah, for Allah knoweth well the secrets of your hearts.

(18) Curses were pronounced on those among the Children of Israel who rejected Faith, by the tongue of David and of Jesus the son of Mary: because they disobeyed and persisted in excesses.

(19) obey Allah, and obey the Messenger, and beware (of evil): if ye do turn back, know ye that it is Our Messenger's duty to proclaim (the message) in the clearest manner.

(20) Say: "I would, if I disobeyed my Lord, indeed have fear of the penalty of a Mighty Day.
