وَحَدَّثَنِي مَالِكٌ، عَنْ يَحْيَى بْنِ سَعِيدٍ، عَنْ سَعِيدِ بْنِ الْمُسَيَّبِ، أَنَّ عُمَرَ بْنَ الْخَطَّابِ، اخْتَصَمَ إِلَيْهِ مُسْلِمٌ وَيَهُودِيٌّ فَرَأَى عُمَرُ أَنَّ الْحَقَّ لِلْيَهُودِيِّ فَقَضَى لَهُ فَقَالَ لَهُ الْيَهُودِيُّ وَاللَّهِ لَقَدْ قَضَيْتَ بِالْحَقِّ . فَضَرَبَهُ عُمَرُ بْنُ الْخَطَّابِ بِالدِّرَّةِ ثُمَّ قَالَ وَمَا يُدْرِيكَ فَقَالَ لَهُ الْيَهُودِيُّ إِنَّا نَجِدُ أَنَّهُ لَيْسَ قَاضٍ يَقْضِي بِالْحَقِّ إِلاَّ كَانَ عَنْ يَمِينِهِ مَلَكٌ وَعَنْ شِمَالِهِ مَلَكٌ يُسَدِّدَانِهِ وَيُوَفِّقَانِهِ لِلْحَقِّ مَادَامَ مَعَ الْحَقِّ فَإِذَا تَرَكَ الْحَقَّ عَرَجَا وَتَرَكَاهُ .
Malik related to me from Yahya ibn Said from Said ibn al-Musayyabthat Umar ibn al-Khattab had a dispute brought to him between a muslimand a jew. Umar saw that the right belonged to the jew and decided inhis favour. The jew said to him, "By Allah! You have judgedcorrectly.'' So Umar ibn al-Khattab struck him with a whip and said,"How can you be sure." The jew said to him, "We find that there is nojudge who judges correctly but that there is an angel on his rightside and an angel on his left side who guide him and give him successin the truth as long as he is with the truth. When he leaves thetruth, they rise and leave him." Translation Not Available
