Hadith.3221 - Abu Abdullah Imam Jafar ibn Muhammad Al-Sadiq (as) said: "The judges are four: three are in the Fire, and one is in Paradise. A man who judges unjustly while he knows is in the Fire. A man who judges unjustly while he does not know is in the Fire. A man who judges justly while he does not know is in the Fire. And a man who judges justly while he knows is in Paradise." Al-Sadiq (as) also said: "Judgment is of two kinds: the judgment of Allah (swt), the Mighty and Majestic, and the judgment of the people of ignorance. Whoever deviates from the judgment of Allah (swt), the Mighty and Majestic, has judged by the judgment of the people of ignorance. And whoever judges for two dirhams contrary to what Allah (swt), the Mighty and Majestic, has revealed has indeed disbelieved in Allah (swt), the Exalted."
