Hadith on Backbiting: Horrific punishment in Hellfire for backbiting

Anas ibn Malik reported: The Messenger of Allah, peace and blessings be upon him, said, “When I was taken on my night journey, I passed by people who had metal hooks in their hands and they were clawing at their faces and necks. I said: Who are these, O Gabriel? Gabriel said: These are the ones who ‘eat the flesh of people’ (49:12) and attack their honor.”
