Question To Imaam Muhammad Bin Saaleh Al-Uthaymeen (rahimahullaah):

When a Muslim shows disapprove of evil (committed by) another person, he (i.e. the doer of the evil) replies to him saying, ‘’You are intrusive’’ or ‘’Do not interfere in that which does not concern you’’. Is this speech correct in such an instance and what should be the reply to (this person)?

Answer:

This speech of his is incorrect. To say to a person who disapproves of his evil that ‘’You are intrusive’’ or ‘’This is not your concern’’. This is not correct because Allaah (The Most High) commanded us forbid evil and enjoin good. It is obligatory upon us to enjoin good and forbid evil according to our ability, whether the one who is commanded or prohibited likes it or not. And he (i.e. the one who rejects the evil) should reply to him (saying), ‘’Indeed, this concerns me because Allaah has commanded me to enjoin good and forbid evil, and that is because the believer to another believer is like a solid building- one part supporting the other. So that which concerns a Muslim is a concern of his brother (i.e. in this instance). [Source: Al-Manaahiy Al-Laf-Dhiyyah’ Page 144]
