The theory of interpretive validity, as one of the most important foundations of interpretation, plays a key role in the field of understanding and interpreting the Holy Qur'an, and it is formed in the space of two-way communication between the master and the slave and determining the duty of the slave towards the master. The conflict and difference between usulists and commentators on the authenticity of suspicion, especially suspicion in education and especially in the field of interpretation of the Holy Qur'an, has led to the emergence of the theory of authenticity in interpretation. Suspicion resulting from reliable methods such as suspicion resulting from reliable news, the appearance of books, consensus and the like are called special suspicion. Some scholars agree with the theory of authenticity in interpretation and others disagree.
