أَخْبَرَنَا الْقَاسِمُ بْنُ زَكَرِيَّا بْنِ دِينَارٍ، قَالَ حَدَّثَنَا عُبَيْدُ اللَّهِ بْنُ مُوسَى، قَالَ أَنْبَأَنَا عَلِيٌّ، - وَهُوَ ابْنُ صَالِحٍ - عَنْ سِمَاكٍ، عَنْ عِكْرِمَةَ، عَنِ ابْنِ عَبَّاسٍ، قَالَ كَانَ قُرَيْظَةُ وَالنَّضِيرُ وَكَانَ النَّضِيرُ أَشْرَفَ مِنْ قُرَيْظَةَ وَكَانَ إِذَا قَتَلَ رَجُلٌ مِنْ قُرَيْظَةَ رَجُلاً مِنَ النَّضِيرِ قُتِلَ بِهِ وَإِذَا قَتَلَ رَجُلٌ مِنَ النَّضِيرِ رَجُلاً مِنْ قُرَيْظَةَ أَدَّى مِائَةَ وَسْقٍ مِنْ تَمْرٍ فَلَمَّا بُعِثَ النَّبِيُّ صلى الله عليه وسلم قَتَلَ رَجُلٌ مِنَ النَّضِيرِ رَجُلاً مِنْ قُرَيْظَةَ فَقَالُوا ادْفَعُوهُ إِلَيْنَا نَقْتُلْهُ . فَقَالُوا بَيْنَنَا وَبَيْنَكُمُ النَّبِيُّ صلى الله عليه وسلم . فَأَتَوْهُ فَنَزَلَتْ { وَإِنْ حَكَمْتَ فَاحْكُمْ بَيْنَهُمْ بِالْقِسْطِ } وَالْقِسْطُ النَّفْسُ بِالنَّفْسِ ثُمَّ نَزَلَتْ { أَفَحُكْمَ الْجَاهِلِيَّةِ يَبْغُونَ } .
It was narrated from Simak, from 'Ikrimah, that Ibn 'Abbas said: "There were (the two tribes of) Quraizah and An-Nadir, and An-Nadir was nobler than Quraiaah. If a man of Quraizah Killed a man of An-Nadir, he would be killed in return, but if a man of An-Nadir killed a man of Quraizah, he would pay a Diyah of one hundred Wasqs of dates. When An-Nadir killed a man of Quraizah, and they said: 'Hand him over to us and we will kill him.' They said: 'Between us and you (as judge) is the Prophet.' So they came to him, then the following was revealed: "And if you judge, judge with justice between them."[3] Al-Qisl (justice) means a soul for a soul. Then the following was revealed: "Do they then seek the judgment of (the days of) Ignorance?"[4] Translation Not Available
