It is narrated from Ibn Abi Bakrah that Sayyiduna Abu Bakrah (may Allah be pleased with him) wrote a letter to one of his sons, who was a judge in the region of Sijistan: "Amma ba'd! When you are in a state of anger, do not judge between two people, because the Messenger of Allah (peace and blessings be upon him) said: No man or ruler should judge between two individuals while in a state of anger."
