عَنْ سَعِيدِ بْنِ الْمُسَيَّبِ: أَنَّ عُمَرَ بْنَ الْخطاب قَتَلَ نَفَرًا خَمْسَةً أَوْ سَبْعَةً بِرَجُلٍ وَاحِدٍ قَتَلُوهُ قَتْلَ غِيلَةٍ وَقَالَ عُمَرُ: لَوْ تَمَالَأَ عَلَيْهِ أَهْلُ صَنْعَاءَ لَقَتَلْتُهُمْ جَمِيعًا. رَوَاهُ مَالِكٌ وروى البُخَارِيّ عَن ابْن عمر نَحوه
Translation
Sa'id ibn al-Musayyab reported: Umar ibn al-Khattab executed five or seven people for one man whom they had killed treacherously. Umar said: ‘If the people of Sana'a had conspired together against him, I would have executed them all.’ Malik transmitted it. Al-Bukhari transmitted a similar report from Ibn Umar.
