The judge must equally be fully aware of the penalties (if any) prescribed for it, and the best ways and circumstances to exercise personal discretion in different cases in line with the Wish of Allah. None, apparently, is as competent in these fields as ‘Ali. At this point, it is apposite to quote this groundbreaking riwayah referenced by al-Hafiz Ibn Kathir (d.
Abi Barrah from Abu al-Tufayl that he heard ‘Ali; and IT IS ALSO AUTHENTICALLY TRANSMITTED through many chains that Amir al-Muminin ‘Ali b. Abi Talib climbed the pulpit of Kufah and said, “ You will not ask me about ANY verse in the Book of Allah, or about ANY Sunnah from the Messenger of Allah, except that I will inform you about that .”[^5] None of the Sahabah was ever able to make a similar claim!
Secondly, justice must be administered with utmost fairness and equity: وإن حكمت فاحكم بينهم بالقسط If you judge, judge between them with fairness and equity.[^6] This verse allows the use of personal discretion in the administration of justice, especially in all cases where no divinely fixed penalties or judgments are available. But even then, it also reiterates the notion that the judge must know everything in the Qur’an and the Sunnah!
Full knowledge of both is required to determine whether or not there is a fixed penalty or judgment concerning a particular case. If there is none, then the judge uses his discretion. Where the judge does not know whether Allah has already fixed the judgment for the issue before him – due to an insufficient knowledge of the Book and the Tradition - he is most likely to effect a miscarriage of justice, without even realizing it!
Moreover, the judge must give his judgments with the best interests of fairness and equity at heart. This is the second message of the above verse. Where there is a divinely fixed penalty or judgment, he must apply it in the fairest and most equitable manners.
