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.‏
