باب مَا يُكْرَهُ مِنْ حَمْلِ السِّلاَحِ فِي الْعِيدِ وَالْحَرَمِ
Sahih al-Bukhari 967

Narrated Sa`id bin `Amr bin Sa`id bin Al-`Aas:

Al-Hajjaj went to Ibn `Umar while I was present there. Al-Hajjaj asked Ibn `Umar, "How are you?" Ibn `Umar replied, "I am all right," Al-Hajjaj asked, "Who wounded you?" Ibn `Umar replied, "The person who allowed arms to be carried on the day on which it was forbidden to carry them (he meant Al-Hajjaj)."

حَدَّثَنَا أَحْمَدُ بْنُ يَعْقُوبَ، قَالَ حَدَّثَنِي إِسْحَاقُ بْنُ سَعِيدِ بْنِ عَمْرِو بْنِ سَعِيدِ بْنِ الْعَاصِ، عَنْ أَبِيهِ، قَالَ دَخَلَ الْحَجَّاجُ عَلَى ابْنِ عُمَرَ وَأَنَا عِنْدَهُ، فَقَالَ كَيْفَ هُوَ فَقَالَ صَالِحٌ‏.‏ فَقَالَ مَنْ أَصَابَكَ قَالَ أَصَابَنِي مَنْ أَمَرَ بِحَمْلِ السِّلاَحِ فِي يَوْمٍ لاَ يَحِلُّ فِيهِ حَمْلُهُ، يَعْنِي الْحَجَّاجَ‏.‏
