'Utayy ibn Damura said, "I saw with Ubay a man who was attributing himself (in lineage) with an attribution of Jahiliyyah, so Ubay told him to bite his father's male organ and did not speak figuratively (i.e. was explicit). So his companions looked at him. He said, 'It appears that you disapprove of it.' Then he said,
'I will never show apprehension to anyone with regards to this. Verily, I heard the Prophet, may Allah
bless him and grant him peace, say, "Whomever attributes himself (in lineage) with an attribution of Jahiliyyah, then tell him to bite his father's male organ and do not speak figuratively (i.e. be explicit)." ' "
Jabir ibn 'Abdullah reported that the Messenger of Allah, may Allah
bless him and grant him peace, passed through the market, entering from
part of the high part of the city and the people were on both sides of
him. He passed by a dead one-eared goat and reached out and took its ear.
Then he said, "Who would like to buy this for a dirham?" They said, "Why
would we want it when it is worthless? What would we do with it?" He said,
"Would you like to have it?" "No," they replied. He asked them that three
times and they said, "No, by Allah! If it were alive, it would have a defect
as it only has one ear. Why would we want it when it is dead?" The Prophet
said, "By Allah, this world is less in the sight of Allah than this goat
is to you."
He also said, "One of the slaves of the Ansar had a son whom he
named Muhammad, The Ansar said, 'We will not give you the kunya of the
Messenger of Allah until we have sat in the road and asked the Prophet
about the Final Hour.' The Prophet said, 'You have come to me to ask me
about the Hour?' 'Yes,' we replied. He said, 'There is no one alive now
who will see it, even if he lives a hundred years.' We said, 'A slave of
the Ansar has had a son and named him Muhammad. The Ansar said, "We will
not call you by the kunya of the Messenger of Allah."' The Prophet said,
'You have done well. Call yourselves with my name, but do not use my kunya.'"
