What is the criterion for backbiting?

Question:
The questioner asks: What are the criteria for backbiting that do not make us sinful?

Answer:
There is no backbiting that does not make you sinful; all backbiting makes you sinful. However, there are things where it is permissible to mention faults for the sake of public benefit. For example, if you complain about a person who delays paying your right, you complain to the judge because you say, "He is delaying, he ate my right, he wronged me." This falls under the category of complaint, and it is permissible because it leads to obtaining the right.
It leads to obtaining the right. It is permissible to go to the men of Hisbah (public order) and to the Committee for Promoting Virtue and Forbidding Vice and say, "So-and-so is doing such and such," so that they follow up and take action against him. This is for the sake of public benefit; the benefit in this is stronger. Yes, if the benefit is stronger than the harm, there is no harm. Yes.
