Question: If someone has backbitten or slandered another, how can he repent of his sin? Should he seek the consent of the backbitten person?

 Answer: He should repent of this great sin he has committed, ask Allah for forgiveness, refute the slander, seek forgiveness from the backbitten/slandered person, and if it is not possible or culminates in a vile consequence, ask Allah to forgive the wronged person.
