Warning People Against a Fasiq Man

بسم الله الرحمن الرحيم

Q 6: is warning people against a man who is known to be immoral, considered Ghibah (backbiting) that a person will be punished for on Doomsday?

A: If the reality is as mentioned, then it will be permissible, if you do so to warn people against his evil deeds so that he may not deceive those who do not know him. Yet, it will not be permissible, if you do so just to pass the time or have fun.
May Allah grant us success! May peace and blessings be upon our Prophet Muhammad, his family and Companions!
