The word(s) "obedient" appears 74 time(s) in 69 verse(s) in Quran in Mohsin Khan translation.

(51) "Except Your chosen slaves amongst them (i.e. faithful, obedient, true believers of Islamic Monotheism)."

(52) Is one who is obedient to Allah, prostrating himself or standing (in prayer) during the hours of the night, fearing the Hereafter and hoping for the Mercy of his Lord (like one who disbelieves)? Say: "Are those who know equal to those who know not?" It is only men of understanding who will remember (i.e. get a lesson from Allah's Signs and Verses).

(53) That is (the Paradise) whereof Allah gives glad tidings to His slaves who believe (in the Oneness of Allah - Islamic Monotheism) and do righteous good deeds. Say (O Muhammad صلى الله عليه و سلم): "No reward do I ask of you for this except to be kind to me for my kinship with you." And whoever earns a good righteous deed, We shall give him an increase of good in respect thereof. Verily, Allah is Oft-Forgiving, Most Ready to appreciate (the deeds of those who are obedient to Him).

(54) 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).

(55) And he ['Îsa (Jesus), son of Maryam (Mary)] shall be a known sign for (the coming of) the Hour (Day of Resurrection) [i.e. 'Isa's (Jesus) descent on the earth]. Therefore have no doubt concerning it (i.e. the Day of Resurrection). And follow Me (Allah) (i.e. be obedient to Allah and do what He orders you to do, O mankind)! This is the Straight Path (of Islamic Monotheism, leading to Allah and to His Paradise).

(56) We created them not except with truth (i.e. to examine and test those who are obedient and those who are disobedient and then reward the obedient ones and punish the disobedient ones), but most of them know not.

(57) Therefore be patient (O Muhammad صلى الله عليه وسلم) as did the Messengers of strong will and be in no haste about them (disbelievers). On the Day when they will see that (torment) with which they are promised (i.e. threatened, it will be) as if they had not stayed more than an hour in a single day. (O mankind! this Qur'an is sufficient as) a clear Message (or proclamation to save yourself from destruction). But shall any be destroyed except the people who are Al-Fasiqun (the rebellious against Allah's Command, the disobedient to Allah)?

(58) (So were) the people of Nuh (Noah) before them. Verily, they were a people who were Fasiqun (rebellious, disobedient to Allah).

(59) Has not the time come for the hearts of those who believe (in the Oneness of Allah - Islamic Monotheism) to be affected by Allah's Reminder (this Qur'an), and that which has been revealed of the truth, lest they become as those who received the Scripture [the Taurat (Torah) and the Injeel (Gospel)] before (i.e. Jews and Christians), and the term was prolonged for them and so their hearts were hardened? And many of them were Fasiqun (the rebellious, the disobedient to Allah).

(60) And indeed, We sent Nuh (Noah) and Ibrahim (Abraham), and placed in their offspring Prophethood and Scripture. And among them there are some who are guided; but many of them are Fasiqun (rebellious, disobedient to Allah).
