๐ Ibn Umar RadhiAllahu 'anhu narrated: Allah's noble Messenger Muhammad SallAllahu 'alaihi wa sallam said, “Whoever argues in favor of falsehood and he knows it, Allah will continue to be displeased with him until he stops. Whoever says something about a believer that is not true, Allah will lodge him in a sinkhole until he recants what he has said.”

๐ Abdullah ibn Amr RadhiAllahu 'anhu narrated: They mentioned a man in front of the Messenger of Allah SallAllahu 'alaihi wa sallam and they said, “He only eats if he is fed! He only moves if he is made to move!” The Prophet SallAllahu 'alaihi wa sallam said, “You have backbitten him.” They said, “We only said what is true about him.” The Prophet SallAllahu 'alaihi wa sallam said, “It is enough sin to mention bad things about your brother.”
In another narration, the Prophet SallAllahu 'alaihi wa sallam said, “If what you said about him were not true, you would have slandered him.”
