The word(s) "obedience" appears 24 time(s) in 24 verse(s) in Quran in Muhammad Habib Shakir translation.

(21) And know that among you is Allah's Apostle; should he obey you in many a matter, you would surely fall into distress, but Allah has endeared the faith to you and has made it seemly in your hearts, and He has made hateful to you unbelief and transgression and disobedience; these it is that are the followers of a right way.

(22) Have you not seen those who are forbidden secret counsels, then they return to what they are forbidden, and they hold secret counsels for sin and revolt and disobedience to the Apostle, and when they come to you they greet you with a greeting with which Allah does not greet you, and they say in themselves: Why does not Allah punish us for what we say? Hell is enough for them; they shall enter it, and evil is the resort.

(23) O you who believe! when you confer together in private, do not give to each other counsel of sin and revolt and disobedience to the Apostle, and give to each other counsel of goodness and guarding (against evil); and be careful of (your duty to) Allah, to Whom you shall be gathered together.

(24) And they were not enjoined anything except that they should serve Allah, being sincere to Him in obedience, upright, and keep up prayer and pay the poor-rate, and that is the right religion.
