Quranic arguments for the narration of the obligation to follow and the sanctity of opposition to the Prophet (PBUH) and the divine saints from the point of view of Shiite and Sunni commentators

The source of sovereignty and obedience is God Almighty, and any sovereignty from other than God is void and oppressive; unless during the reign of God and with His permission, it is like the guardianship of the prophets and saints. Now the question is what are the reasons for the necessity of obedience or sanctity of opposition to the Prophet (PBUH) and the divine saints?  Analytical and descriptive study of this issue shows its special approval in the view of reason and sharia, acting on the words and manners of the Prophet (PBUH) in addition to the approval of reason, has also been approved by Islam. The words of the Prophet (PBUH) and the saints must precede personal intentions, otherwise the person, although he may be considered as a believer, but in fact such a person is a hypocrite or ignorant of the truth of religion and lacks faith.
