Sin of efficacy to knowledge on vices Quranicly studied

There are some obstacles on the way of knowledge of which one can refer to sin. As is understood in Quranic verses and traditions, privation of knowledge, its destruction and conversion is due to the consequences of sins. Sin would lead to human heart conversion due to which virtue seems to be vice and vice to be virtue. There can be presented different explanations on this conversion. On the Quranic teachings, penetrating human feelings and affections, sin brings about changes in thoughts and, using perceptive faculty begins to devise one`s inner life and converse the truths. Insisting on sin would cause human reason to be replaced with imagination. In this way, fallacy happens and true knowledge turns to be nothing.
