we come under the control of Satan who rules us totally.

"Certain sins cause us to be deprived of the Wilayah of Allah and love of Ahlulbayt (A) and lead us to the Wilayah of Satan. After this we come under the control of Satan who rules us totally. Let us take refuge with Allah from such a doom. Hazrat Imam Ja’far al-Sadiq (A) said: “If a person slanders a believer to expose his faults to the public, or to insult him, Allah expels him from His Wilayah and leaves him to the Wilayah of Satan.””
