Story of how the Caliph ʿUmar ؓ suppressed his anger when he was unjustly accused
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."
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۔
