Uyaina bin Hisn bin Hudhaifa bin Badr came and stayed (at Medina) with his nephew Al-Hurr bin Qais bin Hisn 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 my nephew! Have you an approach to this chief so as to get for me the permission to see him?" His nephew said, "I will get permission for you to see him." (Ibn ʿAbbas added: ) So he took permission for 'Uyaina,

And when the latter entered, he said, "O the son of Al-Khattab! By Allah, you neither give us sufficient provision nor judge among us with justice." On that ʿUmar became so furious that he intended to harm him. Al-Hurr, said, "O Chief of the Believers!" Allah said to His Apostle 'Hold to forgiveness, command what is good (right), and leave the foolish (i.e. do not punish them).' (7.199) and this person is among the foolish." By Allah, ʿUmar did not overlook that Verse when Al-Hurr recited it before him, and ʿUmar said to observe (the orders of) Allah's Book strictly."  

قَدِمَ عُيَيْنَةُ بْنُ حِصْنِ بْنِ حُذَيْفَةَ بْنِ بَدْرٍ فَنَزَلَ عَلَى ابْنِ أَخِيهِ الْحُرِّ بْنِ قَيْسِ بْنِ حِصْنٍ وَكَانَ مِنَ النَّفَرِ الَّذِينَ يُدْنِيهِمْ عُمَرُ وَكَانَ الْقُرَّاءُ أَصْحَابَ مَجْلِسِ عُمَرَ وَمُشَاوَرَتِهِ كُهُولاً كَانُوا أَوْ شُبَّانًا۔ فَقَالَ عُيَيْنَةُ لاِبْنِ أَخِيهِ يَا ابْنَ أَخِي هَلْ لَكَ وَجْهٌ عِنْدَ هَذَا الأَمِيرِ فَتَسْتَأْذِنَ لِي عَلَيْهِ قَالَ سَأَسْتَأْذِنُ لَكَ عَلَيْهِ۔ قَالَ ابْنُ عَبَّاسٍ فَاسْتَأْذَنَ لِعُيَيْنَةَ۔

فَلَمَّا دَخَلَ قَالَ يَا ابْنَ الْخَطَّابِ وَاللَّهِ مَا تُعْطِينَا الْجَزْلَ وَمَا تَحْكُمُ بَيْنَنَا بِالْعَدْلِ۔ فَغَضِبَ عُمَرُ حَتَّى هَمَّ بِأَنْ يَقَعَ بِهِ۔ فَقَالَ الْحُرُّ يَا أَمِيرَ الْمُؤْمِنِينَ إِنَّ اللَّهَ تَعَالَى قَالَ لِنَبِيِّهِ ﷺ {خُذِ الْعَفْوَ وَأْمُرْ بِالْعُرْفِ وَأَعْرِضْ عَنِ الْجَاهِلِينَ} وَإِنَّ هَذَا مِنَ الْجَاهِلِينَ۔ فَوَاللَّهِ مَا جَاوَزَهَا عُمَرُ حِينَ تَلاَهَا عَلَيْهِ وَكَانَ وَقَّافًا عِنْدَ كِتَابِ اللَّهِ۔
