Hypocrisy in Islam is a serious sickness and a great crime. Hypocrisy means making an outward display of Islam whilst inwardly concealing disbelief.

Openly flaunting one`s sins implies disrespect towards Allah and His Messenger, and the righteous believers, and is a type of stubborn provocation. Concealing sin protects one against being disrespectful in this manner, because sin brings humiliation upon the people who commit it.

Speaking about your sin and flaunting it openly in front of your friends is prohibited in Islam and is a major sin. Exposing sins in Islam is one of the ways of spreading immorality among the Muslims, encouraging evil and tempting others to do similar things.
