If he shoots game and it falls into water

Sayyiduna Abdullah (bin Mas'ud) (may Allah be pleased with him) said: When you shoot game and it falls into water, do not eat it, for I fear that the water may have killed it. And if you shoot game and it falls from a mountain, do not eat it, for I fear that its death may have been caused by the fall.

Something similar is reported from al-Hasan.
