A man came to Ibn `Umar and asked about `Uthman and Ibn `Umar mentioned his good deeds and
said to the questioner. "Perhaps these facts annoy you?" The other said, "Yes." Ibn `Umar said, "May
Allah stick your nose in the dust (i.e. degrade you)!' Then the man asked him about `Ali. Ibn `Umar
mentioned his good deeds and said, "It is all true, and that is his house in the midst of the houses of
the Prophet. Perhaps these facts have hurt you?" The questioner said, "Yes." Ibn `Umar said, "May
Allah stick your nose in the dust (i.e. degrade you or make you do things which you hate) ! Go away
and do whatever you can against me."
