While on the journey of Mi’raaj, Rasulullah (sallallahu ‘alaihi wasallam) passed by a group of people with copper fingernails. They were using their copper nails to scrape and peel off the skin from their faces and chests. When Rasulullah (sallallahu ‘alaihi wasallam) enquired from Hazrat Jibreel (‘alaihis salaam) regarding who these people were, Hazrat Jibreel (‘alaihis salaam) replied, “These are the people who used to consume the flesh of others.” In other words, they are those people who would backbite others and attack their honor.
