Obeying the Last Prophet in Holy Quran

the Messenger is responsible for expressing verses and divine commandments. An Islamic nation is responsible for understanding and accepting those commandments. Indeed, the reality of obedience is the attempt to reach to the Messenger’s goal. The responsibility of the last prophet is the conspicuous invitation (to believe) and the nation’s duty is obedience. The believers’ obedience will cause the acceptance of pray, unity and eluding of sin and disobedience will cause this world and hereafter’s suffering. Thus obeying the Prophet is one of the divine trials for the believers.
