The word(s) "obeys" appears 18 time(s) in 17 verse(s) in Quran in Mohsin Khan translation.

(1) And how would you disbelieve, while unto you are recited the Verses of Allah, and among you is His Messenger (Muhammad صلى الله عليه وسلم)? And whoever holds firmly to Allah, (i.e. follows Islam - Allah's Religion, and obeys all that Allah has ordered, practically), then he is indeed guided to the Right Path.

(2) These are the limits (set by) Allah (or ordainments as regards laws of inheritance), and whosoever obeys Allah and His Messenger (Muhammad صلى الله عليه وسلم) will be admitted to Gardens under which rivers flow (in Paradise), to abide therein, and that will be the great success.

(3) And whosoever disobeys Allah and His Messenger (Muhammad صلى الله عليه وسلم), and transgresses His limits, He will cast him into the Fire, to abide therein; and he shall have a disgraceful torment.

(4) He who obeys the Messenger (Muhammad صلى الله عليه وسلم), has indeed obeyed Allah, but he who turns away, then we have not sent you (O Muhammad صلى الله عليه وسلم) as a watcher over them.

(5) This is because they defied and disobeyed Allah and His Messenger. And whoever defies and disobeys Allah and His Messenger, then verily, Allah is Severe in punishment.

(6) "O my Lord! They have indeed led astray many among mankind. But whoso follows me, he verily is of me. And whoso disobeys me, still You are indeed Oft-Forgiving, Most Merciful.

(7) And be not like her who undoes the thread which she has spun, after it has become strong, by taking your oaths as a means of deception among yourselves, lest a nation should be more numerous than another nation. Allah only tests you by this [i.e who obeys Allah and fulfils Allah's Covenant and who disobeys Allah and breaks Allah's Covenant]. And on the Day of Resurrection, He will certainly make clear to you that wherein you used to differ [i.e. a believer confesses and believes in the Oneness of Allah and in the Prophethood of Prophet Muhammad صلى الله عليه و سلم which the disbeliever denies and that is their difference amongst them in the life of this world] .

(8) And thus do We requite him who transgresses beyond bounds [i.e. commits the great sins and disobeys his Lord (Allah) and believes not in His Messengers, and His revealed Books, like this Qur'an], and believes not in the Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) of his Lord; and the torment of the Hereafter is far more severe and more lasting.

(9) And whosoever obeys Allah and His Messenger (صلى الله عليه وسلم), fears Allah, and keeps his duty (to Him), such are the successful.

(10) It is not for a believer, man or woman, when Allah and His Messenger have decreed a matter that they should have any option in their decision. And whoever disobeys Allah and His Messenger, he has indeed strayed into a plain error.
