Question: Is it permissible to mention peoples’ names and characters when one wants to criticise them and their thinking?
Response: If someone writes something that contradicts the pure Sharee’ah, and distributes that material, or if he propagates that view in the media, it becomes compulsory to refute him and expose the falsehood of what he says. There is nothing wrong in mentioning that person’s name or in warning people about him if he calls to innovation, shirk, or if he calls people to what Allaah has prohibited or to disobedience. Until this day, there are knowledgeable and believing people from the callers to the truth and bearers of the Sharee’ah fulfilling this obligation, sincerely for Allaah (Subhaanahu wa Ta’aala) and for the benefit of His servants, rebuking the wrong, inviting to the truth, warning others against those who propagate falsehood and destructive rhetoric.
And Allaah is the Expounder of [all] success.
