Mukhtasar Muslim (Abridged) 1055 — Judge should not rule while angry

‘Sayyiduna Abdur Rahman bin Abi Bakrah says that’ my father dictated to Ubaidullah bin Abi Bakrah, who was the judge of Sijistan, and I wrote it down, that you should not judge between two men when you are angry, because I heard the Messenger of Allah (peace and blessings of Allah be upon him) say, he (peace be upon him) used to say that no man should judge between two people when he is in a state of anger.
