'Uyaina bin Hisn bin Hudhaifa came and stayed with his nephew Al-Hurr bin Qais who was one of those whom ʿUmar used to keep near him, as the Qurra' (learned men knowing Qur'an by heart) were the people of ʿUmar'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 ʿUmar 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 ʿUmar 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, ʿUmar did not overlook that Verse when Al-Hurr recited it before him; he observed (the orders of) Allah's Book strictly.
