Saeed bin Musayab reported,

A Muslim and a Jew brought a dispute before Umar bin Khattab. Umar saw that the right of the matter lay with the Jew, so he ruled in his favor.The Jew said to him, "By Allah, you have judged rightly."Umar bin Khattab struck him with his whip and said, "And how would you know that?"The Jew replied, "We find in our scriptures that there is no judge who judges rightly but that an angel stands at his right and an angel at his left, guiding him and keeping him true to what is right, so long as he holds to what is right. But when he abandons the truth, the two angels ascend and leave him."

و حدثني مالك عن يحيى بن سعيد

عن سعيد بن المسيب

أن عمر بن الخطاب اختصم إليه مسلم ويهودي فرأى عمر أن الحق لليهودي فقضى له فقال له اليهودي والله لقد قضيت بالحق فضربه عمر بن الخطاب بالدرة ثم قال وما يدريك فقال له اليهودي إنا نجد أنه ليس قاض يقضي بالحق إلا كان عن يمينه ملك وعن شماله ملك يسددانه ويوفقانه للحق ما دام مع الحق فإذا ترك الحق عرجا وتركاه
