Arabic (Original)
حَدَّثَنَا أَبُو سَلَمَةَ قَالَ أَخْبَرَنَا بَكْرُ بْنُ مُضَرَ عَنْ يَزِيدَ بْنِ عَبْدِ اللَّهِ بْنِ أُسَامَةَ بْنِ الْهَادِ عَن مُحَمَّدِ بْنِ إِبْرَاهِيمَ عَنْ بُسْرِ بْنِ سَعِيدٍ عَنْ أَبِي قَيْسٍ مَوْلَى عَمْرٍو عَنْ عَمْرِو بْنِ الْعَاصِ أَنَّهُ سَمِعَ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَقُولُ إِذَا حَكَمَ الْحَاكِمُ فَاجْتَهَدَ ثُمَّ أَصَابَ فَلَهُ أَجْرَانِ وَإِذَا حَكَمَ وَاجْتَهَدَ ثُمَّ أَخْطَأَ فَلَهُ أَجْرٌ.
English Translation
Abu Salamah narrated to us, he said: Bakr ibn Mudar informed us, from Yazid ibn Abdullah ibn Usamah ibn al-Had, from Muhammad ibn Ibrahim, from Busr ibn Sa'id, from Abu Qays, the freed slave of Amr, from Amr ibn al-'As, that he heard the Messenger of Allah, peace and blessings be upon him, say: 'When a judge passes judgment, exercising his best effort, and is correct, he has two rewards; and when he passes judgment, exercising his best effort, and errs, he has one reward.'
