The Ruling on Pointing Out the Errors of Deceased Scholars

Question:
Or it is said that he corrupted the hearts of people with the doubtful matters that are close to them, which he did not place upon them in his life, or that he judged the rest of Islam and the Muslims, the Muslims, by his books and statements, and whoever writes, if he were to judge him, and he is the one who knows.

Answer:
No, this does not bring any benefit; he is cursed, and this does not bring [benefit], but one should warn against his errors. It is said, "So-and-so committed such and such, and in his such-and-such book he mentioned such and such, so let one beware of it." As for cursing him, disparaging him, and insulting him, there is no need for that. Yes. Because the purpose is to point out his errors so that people are not deceived by them. Or perhaps one of his followers does not know about it, so he should be alerted to it so that he does not continue on his path. As for attacking his personality with cursing, abuse, or insults, there is no need for that.
