Sahih al-Bukhari 3704
Narrated Sa`d bin 'Ubaida:
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."
حَدَّثَنَا مُحَمَّدُ بْنُ رَافِعٍ، حَدَّثَنَا حُسَيْنٌ، عَنْ زَائِدَةَ، عَنْ أَبِي حَصِينٍ، عَنْ سَعْدِ بْنِ عُبَيْدَةَ، قَالَ جَاءَ رَجُلٌ إِلَى ابْنِ عُمَرَ، فَسَأَلَهُ عَنْ عُثْمَانَ،، فَذَكَرَ عَنْ مَحَاسِنِ، عَمَلِهِ، قَالَ لَعَلَّ ذَاكَ يَسُوؤُكَ‏.‏ قَالَ نَعَمْ‏.‏ قَالَ فَأَرْغَمَ اللَّهُ بِأَنْفِكَ‏.‏ ثُمَّ سَأَلَهُ عَنْ عَلِيٍّ، فَذَكَرَ مَحَاسِنَ عَمَلِهِ قَالَ هُوَ ذَاكَ، بَيْتُهُ أَوْسَطُ بُيُوتِ النَّبِيِّ صلى الله عليه وسلم‏.‏ ثُمَّ قَالَ لَعَلَّ ذَاكَ يَسُوؤُكَ‏.‏ قَالَ أَجَلْ‏.‏ قَالَ فَأَرْغَمَ اللَّهُ بِأَنْفِكَ، انْطَلِقْ فَاجْهَدْ عَلَىَّ جَهْدَكَ‏.‏
