The word(s) "obeying" appears 19 time(s) in 19 verse(s) in Quran in Mohsin Khan translation.

(11) Those who were deemed weak will say to those who were arrogant: "Nay, but it was your plotting by night and day: when you ordered us to disbelieve in Allah and set up rivals to Him!" And each of them (parties) will conceal their own regrets (for disobeying Allah during this worldly life), when they behold the torment. And We shall put iron collars round the necks of those who disbelieved. Are they requited aught except what they used to do?

(12) Whosoever desires honour, (power and glory), then to Allah belong all honour, power and glory [and one can get honour, power and glory only by obeying and worshipping Allah (Alone)]. To Him ascend (all) the goodly words, and the righteous deeds exalt it (i.e. the goodly words are not accepted by Allah unless and until they are followed by good deeds), but those who plot evils, theirs will be severe torment. And the plotting of such will perish.

(13) They (Messengers) said: "Your evil omens be with you! (Do you call it "evil omen") because you are admonished? Nay, but you are a people Musrifun (transgressing all bounds by committing all kinds of great sins, and by disobeying Allah).

(14) Say (O Muhammad صلى الله عليه وسلم): "Verily I am commanded to worship Allah (Alone) by obeying Him and doing religious deeds sincerely for His sake only.

(15) It is He Who shows you His Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) and sends down (rain with which grows) provision for you from the sky. And none remembers but those who turn (to Allah in obedience and) in repentance (by begging His Pardon and by worshipping and obeying Him Alone and none else).

(16) (It will be said): "This is what you were promised - (it is) for those oft-returning (to Allah) in sincere repentance, and those who preserve their covenant with Allah (by obeying Him in all what He has ordered, and worshipping none but Allah Alone, i.e. follow Allah's religion - Islamic Monotheism).

(17) And the people of Nuh (Noah) aforetime. Verily, they were more unjust and more rebellious and transgressing [in disobeying Allah and His Messenger Nuh (Noah) عليه السلام].

(18) As a Favour from Us. Thus do We reward him who gives thanks (by obeying Us).

(19) That is (without doubt) the True Day. So, whosoever wills, let him seek a place with (or a way to) His Lord (by obeying Him in this worldly life)!
