Chapter: Can a judge give a judgement in an angry mood?

Abu Bakra wrote to his son who was in Sijistan: 'Do not judge between two persons when you are angry, for I heard the Prophet (ﷺ) saying, "A judge should not judge between two persons while he is in an angry mood."

A man came to Allah's Messenger (ﷺ) and said, "O Allah's Messenger (ﷺ)! By Allah, I fail to attend the morning congregational prayer because so-and-so (i.e., Mu`adh bin Jabal) prolongs the prayer when he leads us for it." I had never seen the Prophet (ﷺ) more furious in giving advice than he was on that day. He then said, "O people! some of you make others dislike (good deeds, i.e. prayers etc). So whoever among you leads the people in prayer, he should shorten it because among them there are the old, the weak and the busy (needy having some jobs to do). (See Hadith No. 90, Vol. 1)

That he had divorced his wife during her menses. `Umar mentioned that to the Prophet. Allah's Apostle became angry and said, "He must take her back (his wife) and keep her with him till she becomes clean from her menses and then to wait till she gets her next period and becomes clean again from it and only then, if he wants to divorce her, he may do so."
