Saeed bin Jubayr reported,

I was with Ibn Umar when the head of a spear struck the sole of his foot, causing his foot to stick to the stirrup. I dismounted and pulled it out. This happened at Mina.When news of this reached Hajjaj, he came to visit him.Hajjaj said, "If only we knew who struck you."Ibn Umar replied, "You are the one who struck me."Hajjaj asked, "How is that?"He answered, "You carried weapons on a day when weapons were not to be carried, and you brought weapons into the Sanctuary when weapons were never brought into the Sanctuary."

عن سعيد بن جبير قال

كنت مع ابن عمر حين أصابه سنان الرمح في أخمص قدمه فلزقت قدمه بالركاب فنزلت فنزعتها وذلك بمنى فبلغ الحجاج فجعل يعوده فقال الحجاج لو نعلم من أصابك فقال ابن عمر أنت أصبتني قال وكيف قال حملت السلاح في يوم لم يكن يحمل فيه وأدخلت السلاح الحرم ولم يكن السلاح يدخل الحرم
