Mu’adh bin Anas (may Allah be pleased with him) reports that the Messenger of Allah (peace and blessings be upon him) said:“Whoever protects the honor of a believer from a hypocrite, Allah will send an angel who will protect his flesh from the fire of Hell on the Day of Resurrection. And whoever accuses a Muslim of something in order to disgrace him, Allah will detain him on the Bridge of Hell until he is cleared of what he said.”Its chain is weak. Narrated by Abu Dawood.
