6) باب بَيَانِ أَجْرِ الْحَاكِمِ إِذَا اجْتَهَدَ فَأَصَابَ أَوْ أَخْطَأَ ‏‏

حَدَّثَنَا يَحْيَى بْنُ يَحْيَى التَّمِيمِيُّ، أَخْبَرَنَا عَبْدُ الْعَزِيزِ بْنُ مُحَمَّدٍ، عَنْ يَزِيدَ بْنِ عَبْدِ، اللَّهِ بْنِ أُسَامَةَ بْنِ الْهَادِ عَنْ مُحَمَّدِ بْنِ إِبْرَاهِيمَ، عَنْ بُسْرِ بْنِ سَعِيدٍ، عَنْ أَبِي قَيْسٍ، مَوْلَى عَمْرِو بْنِ الْعَاصِ عَنْ عَمْرِو بْنِ الْعَاصِ، أَنَّهُ سَمِعَ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ ‏‏ ‏.‏ "‏ إِذَا حَكَمَ الْحَاكِمُ فَاجْتَهَدَ ثُمَّ أَصَابَ فَلَهُ أَجْرَانِ ‏.‏ وَإِذَا حَكَمَ فَاجْتَهَدَ ثُمَّ أَخْطَأَ فَلَهُ أَجْرٌ ‏"
