In verse 120 of Surah Al-An'am, it is emphasized to abandon the outward and inward sins, and it is addressed to human that you must abandon sins, whether they are apparent or hidden. In this article, various interpretations from the point of view of scholars and various traditions of Imams Athar (A.S.) regarding this verse were examined and various cases of their analysis were criticized. One of the very important results of this research is that the meant by apparent sin is a secret sin which is done with body parts and it consists of unseemly acts that happen in secret and away from people's eyes. Because he did not pretend it in the community and did not spread prostitution, therefore it is possible to forgive. But the hidden sin meaning is corrupt and false ideas and its manifestation is in a person who recklessly commits sin in society and disobeys God and it promotes, normalizes and spreads prostitution among the society. Certainly, this person's sin is much heavier and his punishment is more severe. Therefore, the examples of hidden sin are the main promoters and culture makers of sin, such as America, who create and promote corrupt and sinful ideas and also those who want to diminish this enmity and turn it into friendship.
