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
Said b. al-Musayyib told that Umar ibn al-Khattab killed five or seven people for one man whom they had killed treacherously, Umar saying. “If the people of Sana had conspired against him I would have killed them all.”
