Anas (may Allah be pleased with him) narrates: The Messenger of Allah (peace and blessings be upon him) said: "When my Lord took me on the Night Journey, I passed by people who had nails of copper with which they were scratching their faces and chests. I said: 'O Jibreel! Who are these people?' He said: 'These are the ones who used to eat the flesh of people (i.e., backbite them) and attack their honor.'" Its chain is authentic. Narrated by Abu Dawood.
