Narrated Ibn `Abbas: 'Uyaina bin Hisn bin Hudhaifa came and stayed with his nephew Al-Hurr bin Qais who was one of those whom `Umar used to keep near him, as the Qurra' (learned men knowing Qur'an by heart) were the people of `Umar's meetings and his advisors whether they were old or young. 'Uyaina said to his nephew, O son of my brother! You have an approach to this chief, so get for me the permission to see him. Al-Hurr said, I will get the permission for you to see him. So Al-Hurr asked the permission for 'Uyaina and `Umar admitted him. When 'Uyaina entered upon him, he said, Beware! O the son of Al-Khattab! By Allah, you neither give us sufficient provision nor judge among us with justice. Thereupon `Umar became so furious that he intended to harm him, but Al-Hurr said, O chief of the Believers! Allah said to His Prophet: Hold to forgiveness; command what is right; and leave (don't punish) the foolish. (7.199) and this (i.e. 'Uyaina) is one of the foolish. By Allah, `Umar did not overlook that Verse when Al-Hurr recited it before him; he observed (the orders of) Allah's Book strictly.
