Lady Umm Salamah (may Allah be pleased with her) narrates that the Noble Prophet (peace and blessings be upon him) said: "Whoever is put to trial by being made a judge among the people, he should not raise his voice before one of the two parties in a case until he raises his voice before the other party as well (i.e., he should treat both equally)."

Lady Umm Salamah (may Allah be pleased with her) narrates that the Noble Prophet (peace and blessings be upon him) said: "Whoever is put to trial with judging between Muslims should not decide between two parties while he is angry."

It is narrated about Sayyiduna Abu Bakrah, may Allah be pleased with him, that he wrote in a letter to his son, who was a judge in Sijistan: "I heard the Noble Prophet, peace and blessings be upon him, say: 'No judge should decide between two people while angry, and he should not give two judgments in one matter.'"

Abu Sa'id al-Khudri (may Allah be pleased with him) narrates that the Prophet Muhammad (peace be upon him) said: "A judge should give a verdict when he is satiated and has eaten and drunk (i.e., he should not give a verdict in a state of restlessness, anxiety, or mental disturbance)."
