The Most High says, “Those of you who turned back on the day the two hosts met (i.e. the battle of Uhud), it was Shaytaan who caused them to backslide because of some of the sins they had earned.” (Soorah Aal-Imraan (3):155 )
In the battle of Uhud when the archers who had been ordered by the Prophet (sallAllaahu alaihi wa sallam) to remain on the mountain, evacuated and forgot their orders, Shaytaan tempted them to leave their positions.
These aayaat describe what happened in the minds of the archers, imagine then the whole of mankind and their state of mind when they commit a sin. They lose their confidence in their power thus weakening their connections with Allaah.It upsets their equilibrium and firmness becoming subjected to the whisperings of Shaytaan and weakening the connections with Allaah.The confidence of Allaah’s Pardon and Pleasure are reduced.That is when Shaytaan finds a way into his mind driving him to make error upon error becoming further away from safe protection and intense support.
