This is another article in the chapter Enormities from the classical manual on Sharia called Reliance of the Traveller. The articles are posted one by one in the order they are given in the book.
p26.0 THE BAD JUDGE
p26.1 Allah Most High says:
(1) “Whoso does not judge by what Allah has revealed, those are the unbelievers” (Koran 5:44).
(2) “Those who conceal the clear explanations and guidance We have revealed, after We have explained it in the Book to people, are cursed by Allah and those who curse” (Koran 2:159).
p26.2 The Prophet (Allah bless him and give him peace) said:
(1) “One judge shall go to paradise, and two to hell. The judge who knows what is right and judges accordingly shall be in paradise. The one who knows what is right but intentionally judges unjustly will go to hell, and so will the judge who judges without knowledge.”
Anyone who judges without knowledge or evidence from Allah and His messenger regarding the matter he gives an opinion on is subject to this threat.
(2) “Whoever is appointed to judge between people is as though slaughtered without a knife.”
p26.3 It is unlawful for a judge to rule on a case when angry, especially at a litigant. When a judge’s qualities combine an insufficiency of Sacred Knowledge, unworthy intention, bad disposition, and lack of godfearingness, then his destruction is complete and he must resign and hasten to save himself from hell.
