'Utayy ibn Damura said, "I saw a man with my father who was consoling another man in the way people used to console each other in the Jahiliyya. My father bit him and would not use his kunya. His companions looked at my father and he said, 'It appears that you disapprove of that.' He said, 'I will never respect anyone who does this! I heard the Prophet, may Allah bless him and grant him peace, say, "If someone consoles people in the way people consoled each other in the days of the Jahiliyya, then bite him, and do not use his kunya."'"
