Ibn 'Abbas (May Allah be pleased with them) reported: 'Uyainah bin Hisn came to Al-Madinah and stayed with his nephew Hurr bin Qais who was among those whom Umar (May Allah be pleased with him) showed favour to. The knowledgeable people (Qurra'), whether they were old or young, had the privilege of joining Umar's council and he used to consult them'.Uyainah said to Hurr: "My nephew, the Leader of the Believers shows favour to you. Will you obtain permission for me to sit with him?" Hurr asked 'Umar and he accorded permission. When 'Uyainah came into the presence of 'Umar, he addressed him thus: "O son of Khattab, you neither bestow much on us nor deal with us justly"'.Umar (May Allah be pleased with him) got angry and was about to beat him up when Hurr said: ''O Leader of the Believers, Allah said to His Prophet ﷺ: ' Show forgiveness, enjoin what is good, and turn away from the foolish (ie, don't punish them)'. (7:199) This one is from the ignorants. When Hurr recited this, 'Umar became quite motionless in his seat. He always adhered strictly to the Book of Allah. Al-Bukhari.
