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

(41) And when Our Messengers came to Ibrahim (Abraham) with the glad tidings they said: "Verily, we are going to destroy the people of this [Lut (Lot's)] town (i.e. the town of Sodom in Palestine); truly, its people have been Zalimun [wrong-doers, polytheists disobedient to Allah, and who belied their Messenger Lut (Lot)]."

(42) To Him belongs whatever is in the heavens and the earth. All are obedient to Him.

(43) Is then he who is a believer like him who is a Fasiq (disbeliever and disobedient to Allah)? Not equal are they.

(44) And as for those who are Fasiqun (disbelievers and disobedient to Allah), their abode will be the Fire, every time they wish to get away therefrom, they will be put back thereto, and it will be said to them: "Taste you the torment of the Fire which you used to deny."

(45) And whosoever of you is obedient to Allah and His Messenger (صلى الله عليه وسلم), and does righteous good deeds, We shall give her, her reward twice over, and We have prepared for her Rizq Karim (a noble provision - Paradise).

(46) Verily, the Muslims (those who submit to Allah in Islam) men and women, the believers men and women (who believe in Islamic Monotheism), the men and the women who are obedient (to Allah), the men and women who are truthful (in their speech and deeds), the men and the women who are patient (in performing all the duties which Allah has ordered and in abstaining from all that Allah has forbidden), the men and the women who are humble (before their Lord - Allah), the men and the women who give Sadaqat (i.e. Zakat, and alms), the men and the women who observe Saum (fast) (the obligatory fasting during the month of Ramadan, and the optional Nawafil fasting), the men and the women who guard their chastity (from illegal sexual acts) and the men and the women who remember Allah much with their hearts and tongues Allah has prepared for them forgiveness and a great reward (i.e. Paradise).

(47) Certainly, that is how We deal with Al-Mujrimun (polytheists, sinners, disbelievers, criminals, the disobedient to Allah).

(48) Except the chosen slaves of Allah (faithful, obedient, and true believers of Islamic Monotheism).

(49) And (so did) the birds assembled: all obedient to him [Dawud (David)] [i.e. they came and glorified Allah's Praises along with him]. (Tafsir Al-Qurtubi ).

(50) This is so! And for the Taghun (transgressors, the disobedient to Allah and His Messenger - disbelievers in the Oneness of Allah, criminals) will be an evil final return (Fire).
