'Abdallah b. Abu Aufa reported God’s Messenger as saying, “God is with the qadi as long as he is not tyrannical, but when he is He departs from him and the devil attaches himself to him.” A version has, “When he is tyrannical He leaves him to his own devices.”
‘A’isha reported God's Messenger as saying, “The day of resurrection will come to the just qadi and he will wish he had never given judgment between two men about a single date.”*
Ahmad transmitted it.
* He will wish he had never given judgment even about the most insignificant matters.
Said b. al-Musayyib told that a Muslim and a Jew brought a dispute before ‘Umar, and as he considered the Jew was in the right he pronounced judgment in his favour; but when the Jew said, “I swear by God that you have pronounced just judgment,” he struck him with the whip and asked him what caused him to know that. The Jew replied, “I swear by God that we find in the Torah that no qadi judges rightly without having an angel at his right hand and an angel at his left who direct him and dispose him to what is right as long as he adheres to the right; but when he abandons the right they ascend and leave him.”
‘Abdallah b. Mas'ud reported God’s Messenger as saying, “No judge who pronounces judgment among men will fail to come on the day of resurrection with an angel holding the back of his neck. He* will then raise his head to heaven, and if God gives orders to cast him down, he will cast him into an abyss forty years deep."
Ahmad, Ibn Majah, and Baihaqi in Shu'ab al-lman transmitted it.
