حَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، حَدَّثَنَا أَبُو عَوَانَةَ، عَنْ عَبْدِ الْمَلِكِ بْنِ عُمَيْرٍ، عَنْ عَبْدِ الرَّحْمَنِ، بْنِ أَبِي بَكْرَةَ . قَالَ كَتَبَ أَبِي - وَكَتَبْتُ لَهُ - إِلَى عُبَيْدِ اللَّهِ بْنِ أَبِي بَكْرَةَ وَهُوَ قَاضٍ بِسِجِسْتَانَ أَنْ لاَ، تَحْكُمَ بَيْنَ اثْنَيْنِ وَأَنْتَ غَضْبَانُ فَإِنِّي سَمِعْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم يَقُولُ " لاَ يَحْكُمْ أَحَدٌ بَيْنَ اثْنَيْنِ وَهُوَ غَضْبَانُ " .
