Maliks Muwatta Book 25, Hadith Number 1.

Section : Eating Game Killed with Throwing Sticks and by Stones.

Yahya related to me from Malik that Nafi said, “I was at al-Juruf (near Madina) and threw a stone at two birds, and hit them. One of them died, and Abdullah ibn Umar threw it away, and then went to slaughter the other one with an adze. It died before he could slaughter it, so Abdullah threw that one away as well.”
