General Behavior (Kitab Al-Adab)

Dawud :: Book 41 : Hadith 4860

Narrated Anas ibn Malik:

The Prophet (peace_be_upon_him) said: When I was taken up to heaven I passed by people who had nails of copper and were scratching their faces and their breasts. I said: Who are these people, Gabriel? He replied: They are those who were given to back biting and who aspersed people's honour.
