What is the ruling on unintentional wrongdoing, and what is required when conveying incorrect information with the aim of reconciliation, and is it necessary to inform the parties about the misunderstanding?

If speaking about a person is intended for reform or to help change a reprehensible act, and it does not involve falsehood, then there is no harm in it, and it is not forbidden backbiting. However, if it is not for a beneficial purpose, then it is impermissible. If you made a mistake in identifying a person and attributed to them something they did not say, then you must clarify that to those with whom you spoke. Continuing to show kindness to relatives despite their ill-treatment brings great reward, as stated in the Hadith: "If you are as you say, then it is as if you are feeding them hot ashes, and you will continue to have a supporter from Allah against them as long as you remain upon that."
