同士討ち
At Medina, Hudhayfah became a trusted and great companion of Muhammad, participating in all the military engagements except Badr. He participated in the Battle of Uhud with his father. Before the battle, Muhammad left al-Yaman, Hudhayfah's father, and Thabit ibn Waqsh with the other non-combatants because they were both quite old. As the fighting intensified, al-Yaman and his friend decided that despite their age they did not want to miss the opportunity to participate. They quickly prepared for battle and were soon in the thick of the fighting. Thabit ibn Waqsh was killed at the hands of the "mushrikin". The father of Hudhayfah, however, was killed by friendly fire. (Friendly fire is when somebody gets killed by somebody else who is on their side.) As they attacked him, Hudhayfah cried out: "My father! My father! It's my father!"
