It was narrated tht 'Adiyy bin Hatim said:"I said: 'O Messenger of Allah, we are a people who hunt, and one of us may shoot his arrow but (the game) gets way from him for a night or two. What if he follows its tracks, and finds it dead with his arrow in it?" He said: "If you find the arrow in it, and you do not find any sign of predators, and you know that your arrow killed it, then eat it." (Sahih)
