The word(s) "obedience" appears 67 time(s) in 66 verse(s) in Quran in Mohsin Khan translation.

(31) On the Day when He will call you, and you will answer (His Call) with (words of) His Praise and obedience, and you will think that you have stayed (in this world) but a little while!

(32) And (remember) when We told you: "Verily! Your Lord has encompassed mankind (i.e. they are in His Grip)." And We made not the vision which we showed you (O Muhammad as an actual eye-witness and not as a dream on the night of Al-Isra' ) but a trial for mankind, and (likewise) the accursed tree (Zaqqum, mentioned) in the Qur'an. We warn and make them afraid but it only increases them in naught save great disbelief, oppression and disobedience to Allah.

(33) "And befool them gradually those whom you can among them with your voice (i.e. songs, music, and any other call for Allah's disobedience), make assaults on them with your cavalry and your infantry, share with them wealth and children (by tempting them to earn money by illegal ways - usury, or by committing illegal sexual intercourse), and make promises to them." But Satan promises them nothing but deceit.

(34) "Go to Fir'aun (Pharaoh)! Verily, he has transgressed (all bounds in disbelief and disobedience, and has behaved as an arrogant and as a tyrant)."

(35) "Go, both of you, to Fir'aun (Pharaoh), verily, he has transgressed (all bounds in disbelief and disobedience and behaved as an arrogant and as a tyrant).

(36) "Truly, it has been revealed to us that the torment will be for him who denies [believes not in the Oneness of Allah, and in His Messengers.], and turns away (from the truth and obedience of Allah)."

(37) And (all) faces shall be humbled before (Allah), Al-Hayyul-Qayyum (the Ever Living, the One Who sustains and protects all that exists). And he who carried (a burden of) wrongdoing (i.e. he who disbelieved in Allah, ascribed partners to Him, and did deeds of His disobedience), will be indeed a complete failure (on that Day).

(38) And (remember) when We showed Ibrahim (Abraham) the site of the (Sacred) House (the Ka'bah at Makkah) (saying): "Associate not anything (in worship) with Me, [La ilaha illallah (none has the right to be worshipped but Allah) - Islamic Monotheism], and sanctify My House for those who circumambulate it, and those who stand up (for prayer), and those who bow (submit themselves with humility and obedience to Allah), and make prostration (in prayer);"

(39) They swear by Allah their strongest oaths, that if only you would order them, they would leave (their homes for fighting in Allah's Cause). Say: "Swear you not; (this) obedience (of yours) is known (to be false). Verily, Allah knows well what you do."

(40) He said: "O chiefs! Which of you can bring me her throne before they come to me surrendering themselves in obedience?"
