Shari’at Sanglaji, as one of the activists of the contemporary Shia Qur'an-Sufficiency attitude, seeks to narrow the scope of personal exegesis with anything other than the interpretation of the Qur'an to the Qur'an. Updating the religion by purifying it from non-Qur'anic teachings is the ideal of the defenders of this movement. This research critiques this religious rethinking approach by a descriptive-analytical method. Shari’at Sanglaji, through understanding the Qur'anic phrases, concludes that the Nubuwwah and Wilayah Sunnah are not original in anything other than Āyāt al-Aḥkām, and emphasizes the need to interpret the Qur'an in the light of other verses, as the best and only source for the correct interpretation of verses. He considers a non-independent role for the Ahl al-Bayt (AS) in explaining the divine verses and considers them as the commentator of the Prophet’s Sunnah (PBUH), and not the commentator of the Qur’an’s verses. Among the contradictions of this approach with Imamiyyah thoughts are incompatibility with the nature of intercession, a shaky position for the intellect in interpreting verses, and the fallacy of referring to the companions in referring to the interpretation of the Qur'an without any explanation regarding accepting the narrations received from them. Most Imamiyyah theologians emphasize the position of the Prophet and the saints in the direct news of God and organizing the spiritual and social life of the people, as well as the authority that God has given to the Holy Prophet (PBUH) and his esteemed saints. And they consider obedience to the Prophet and the saints necessary because of their immunity from sin and error in personal and social actions. From this perspective, intercession is impossible without God's permission, and the authority of intercession is expressed.
